Question

Ravi drove 693 miles in 11 hours.

At the same rate, how long would it take him to drive 315 miles?

Answer 1

Explanation:

Set up a proportion

693 miles / 11 hours = 315 miles / x hours

Notice that the numerators both have the same units (miles).

Cross multiply

693x = 11 * 315 Combine

693x = 3465 Divide by 693

x = 5

It will take him 5 hours to go 315 miles
