a. How many miles did she drive in one hour?
miles/hour
b. How many hours did she take to drive one mile?
hours/mile

Answer 1

Wally drove 14 miles in one hour, and it took her approximately 0.0714 hours to drive one mile.

Step-by-step explanation:

To answer the student's question about Wally's travel distance and time, we will calculate her driving rate in miles per hour and then determine the time it takes to drive one mile.

Part A: Miles per hour

First, we need to find out how many miles Wally drove in one hour:

To find the driving rate, divide the total miles driven by the total hours driven:
30 2/3 miles ÷ 2 1/3 hours = 14 miles/hour.

This means Wally drove 14 miles in one hour.

Part B: Hours per mile

Next, we will calculate how many hours Wally took to drive one mile:

To find the time per mile, take the reciprocal of the driving rate:
1 ÷ 14 miles/hour = 0.0714 hours/mile.

Therefore, it took Wally approximately 0.0714 hours to drive one mile.
