That means the trip has to be completed in 4 minutes.

And just where does it state that the trip has to be completed in four minutes?

It’s in the question itself. You must average 30mph the whole trip.

30mph is 2 miles per minute. The whole trip is two miles therefore at 15mph going up the hill it’ll take the entire 4 minutes doing the first uphill mile. There is no time left to do the second mile. It’d have to be a “beam me up Scotty” moment.

And just where does it state that the trip has to be completed in four minutes?

The hill is one mile up and one mile down. The total trip is two miles. The average final speed has to be 30 mph. 30 mph means .5 miles per minute. 2 (the number of miles) divided by .5 (the average speed of the entire trip) = 4.
