Question

Suppose your walking rate is 4 feet per second. Write this rate in miles per hour.

Answer 1

Answer: 2.727 miles per hour

Step By Step:

4 ft/sec X 3600 sec/hour = 14400 ft/hour

14400 ft/hour / 5280 ft/mile = 2.727 miles/hour

Answer 2

About 2.72 miles per hour

Explanation:

60 seconds = 1 minute

3,600 seconds = 1 hour

3,600 (4) = 14,400

1 mile = 5,280 feet

14,400 feet = about 2.72 miles
