Question

An elephant can run 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? plz help asap

Answer 1

The expression that can be used to determine how fast an elephant runs in miles per hour is 100 miles per hour

Solution:

Given that,

Distance covered by an elephant in 36 seconds is equal to 1 mile

Therefore, distance covered by the elephant in 1 second is
`(1)/(36)` mile

Therefore, distance covered by the elephant in 60 seconds (60 seconds = 1 minute) is

`(1)/(36) * 60=(5)/(3) \text { miles }`

Therefore, distance covered by the elephant in 60 minute (60 minute = 1 hour) is

`(5)/(3) * 60=100 \text { miles per hour }`

Hence the expression that can be used to determine how fast an elephant runs in miles per hour is 100 miles per hour
