40 miles how long

Question

Hol long does it take to drive 40 miles if the speed limit is 65

Answer 1

I'm assuming the vehicle is being driven at the posted speed limit.

At 65 mph, 65 miles will be driven in 60 minutes, which is 1.083 miles per minute.

At 65 mph, 40 miles will be driven in 40 miles / 1.083 miles per minute = 36.923 minutes ~ 37 minutes, where "~" means is approximately equaly to.
