Rick is driving to his friend's house. the speed limit is 35 mph, but he goes 10 over. the trip takes him 20 minutes. how much longer would the trip have taken him if he drove the speed limit?

20 minutes is 1/3 hour.

Rick goes 45 mph for 1/3 hour so a distance of

At 35 mph that would take

That's

2/21 hours

That's about 5.7 minutes longer

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
