Since this post wants to be slick it depends it wasn’t specific on your average mph based on the time you drive or the average based on miles you drive yes by time it’s impossible because if you travel at 90mph on the way home then you cut the time driven home by more then half (example 30 mile trip at 30mph is an hour and the trip back at 90mph is 20 minutes thus not equaling an average of 60 mph according to the time driven “ but according to distance driving it is 90mph because 30 miles at 30 mph and 30 miles at 90mph still averages 60 mph per mile

I drove 30 miles to work at 30mph. I drove 90 miles home (using the disused racetrack past my house) at 90mph. I drove a total of 120 miles in two hours, averaging 60mph

the answer is 90mph. the provided alternative answer makes no sense, for the given prompt.

The question us Phrasen stupid, the question does'nt specify any of it. To me the question only asked for a speed, not anything else

maybe we should practice critical thinking instead of using AI. the distance wasn't specified. you can drive to work 1 mile away at 30mph. in order to return home, 1 mile away, with the goal of averaging 60mph round-trip, you would need to drive 90mph.

This question does not specify distance, nor, more umportantly, does it specify if it is equidistant to and from work. if it is the same distance both ways, yes, it is impossible. However, if it is 10 miles to work, but the route home is 20 miles, then if you drove 120mph, you'd average 60mph over the 30 miles you drove. Another poorly worded "riddle."

90, it’s the same distance, which it is MILES per hour, so the measure speed but based of distance, so 90mph

key :
Just use algebra. let time taken from home to work be t
time taken from work to home be t’
avg speed = total distance / total time
60t/(t+t’) = 60
t/(t+t’) = 1
t=t+t’
t’=0. It is impossible

Trick question. No possible answer.

It’s impossible for the same distance or less if the average speed should double as you already used up all the time in the first half

if you drive home at the speed of light it's basically 60 mph

It’s impossible. You would need to drive home at an infinitely fast speed to average 60 mph for the entire round trip. If the trip to work takes one hour at 30 mph, you’ve already used the entire hour that a 60 mph average would allow for the whole trip. So no matter how fast you drive home, the round-trip average will always be less than 60 mph.

One normally calculates average speed using formula overall average = 2x S1xS2/(S1+S2)…( or you can also work it out yourself on basic principle of average = total distance traveled/total time taken for both legs of journey). 60= 2x30 xS2/(30+S2)… it quickly shows that S2 can only be zero… which indicates formula has failed. This is because the first leg speed of 30 MPH is way too slow so no matter how fast you travel on returns journey, you don’t have enough time to make an overall average of 60MPH. I tried twice using different approaches and couldn’t quite comprehend why I can’t get an answer before I realised this is a trick question.

You should have specified speed or velocity cause they give 2 different answers

To make your average speed 60mph you'd have to drive there at 30 mph and back at 60 mph.

You can’t average 60 mph for the round trip. 😅
If the trip to work is 30 miles at 30 mph, it takes 1 hour.
To average 60 mph over the whole 60-mile round trip, you’d need to complete it in 1 hour total—but you already used 1 hour going there.
So you’d need to drive home infinitely fast. 🚗💨
Answer: It’s impossible.

clutz :
guys this is not a poorly written riddle the distance to and from work is obviously the same distance and lets say its 30 miles to get there that takes 1 hour and if you want 60mph on average the way back would obviously need to take 0 time so its impossible

There isn't an average available the question itself hasn't got enough information in order to calculate an average speed also the variables involved make the question unequatable. so intelligent is creating an equation that is workable not a question that is vaguer than separating mist in dog.😎😇🤔
