Answer 1

Answer:

Required distance between her home and school is 1 kilometre.

Explanation:

Given,

Average walking speed = 4 km / h

From the properties of speed

• Speed = Distance / time taken to cover that distance

Here,

It takes 15 minutes for her to reach her school.

On the basis of the formula given above :

= > 4 km / h = Distance / 15 min

= > 4 km / h x 15 min = Distance

= > 4 km / 60 min x 15 min = Distance

= > 4 km / 4 = Distance

= > 1 km = Distance

Hence the required distance between her home and school is 1 kilometre.

Answer 2

Answer:

4 km / h = Distance / 15 min

4 km / h x 15 min = Distance

4 km / 60 min x 15 min = Distance

4 km / 4 = Distance

1 km = Distance

1 kilometre.
