Question

On a map with a scale of 1 inch = 90 miles, the distance between San Francisco and Phoenix is 10 inches. If Jackson travels at an average rate of 60 miles per hour, how long will it take him to make the trip?

A. 6 hours
B. 9 hours
C. 10 hours
D. 60 hours

Answer 1

To travel from San Francisco to Phoenix, it will take Jackson approximately 15 hours.

Step-by-step explanation:

To calculate how long it will take Jackson to travel from San Francisco to Phoenix, we need to convert the distance on the map to the actual distance. According to the map scale, 1 inch represents 90 miles. Since the distance between San Francisco and Phoenix is 10 inches on the map, we can multiply 10 by 90 to find the actual distance in miles: 10 inches * 90 miles/inch = 900 miles.

Next, we can calculate the time it will take Jackson to travel this distance by using the formula:

Time = Distance / Speed

Given that Jackson's average rate is 60 miles per hour, we can substitute the values into the formula:

Time = 900 miles / 60 mph = 15 hours.
