A man drove his car a distance of 315 miles in 5 hours. If continuing at this rate is possible, he will travel _____ miles in 9 hours.

Answer 1

To solve this problem, we first want to find the unit rate, which is how many miles in one hour. To go from 5 hours to 1 hour, we must divide by 5 so we will also divide 315 by 5. 315/5 = 63.

Now that we know the man drove at a speed of 63 miles per hour, we can multiply 63 miles by 9 to determine how many miles in 9 hours. 63 x 9 = 567

He will travel 567 miles in 9 hours.

Answer 2

First, you will need to find the miles per hour by dividing 315 by 5. Then multiply the mph by 9 to answer the question.

Answer 3

This problem can be solved in several ways but the fastest is to divide 315 by 5 then multiply the answer by 9. The problem is a distance problem D=RT.
