Question

Traveling with a speed of 70 mph, a car covered a distance D miles in T hours. Write an equation that relates the distance D this car travels in T hours. Use the equation to find the distance the car travels between 3:30 p.m. and 5:00 p.m.

Answer 1

Just use the dirt method... Rate times time equals distance... Ok so it is traveling at a speed of 70 mph so that would be the rate (the speed). At first you don't know the distance but then it tells you in the end. So how many hours and minutes is it to get from 3:30 to 5:00? 2 hours and 30 minutes... So you just found the time. Then you times the rate/speed by the time and their you go! You get the distance!
