Question

An ostrich can run at speeds of up to 72 km/h. How long will it take an ostrich to run 1.5 km at this top speed

Answer 1

1.25 minutes.

Explanation:

Given,

Speed of the ostrich = 72 km/h

Distance it has to cover = 1.5 km,

`Time =(Distance)/(Time)`

Thus, the time taken by the ostrich

`=(1.5)/(72)\text{ hours}`

`=(1.5* 60)/(72)\text{ minutes}` ( ∵ 1 hour = 60 minutes )

`=1.25\text{ minutes}`
