Question

Danielle needs to walk 2.5 miles. If she wants to reach her destination in 30 minutes (1/2 hour), how fast does she need to walk?

Answer 1

She needs to walk 5 miles an hour.

Answer 2

She need to walk 5 miles/hr.

Explanation:

Consider the provided information.

Danielle needs to walk 2.5 miles. If she wants to reach her destination in 30 minutes (1/2 hour), we need to find the speed of Danielle.

`Speed=(Distance)/(Time)`

The distance is given 2.5 miles and time is 1/2 hours.

1/2 hours = 0.5 hours

Substitute the respective values in the above formula.

`Speed=(2.5)/(0.5)`

`Speed=(25)/(5)`

`Speed=5`

Hence, she need to walk 5 miles/hr.
