Question

An elephant can run 1/4 of a mile in 36 seconds. At this rate, which expression can be used to determine how fast an elephant runs in miles per hour?

Answer 1

1. First you need to understand that 36 seconds is 1/100 of a mile.
2. An elephant can run 0.25 miles (1/4 of a mile) in 1/100 of a hour.
3. To even this out, multiply 0.25 by 100 to find how many miles per hour an elephant can run (25 miles per hour!)
