Question

boris drove 819 miles in 13 hours. at the same rate, how long would it take him to drive 693 miles?

Explanation:

Step1: Calculate the speed

Speed = Distance / Time. Given distance = 819 miles and time = 13 hours, so speed $s=\frac{819}{13}=63$ miles per hour.

Step2: Calculate the new time

Time = Distance / Speed. Now distance = 693 miles and speed = 63 miles per hour, so time $t=\frac{693}{63}=11$ hours.
