Suppose you are walking home from school. The distance from school to your is home is five kilometers. On foot, you can get home in 25 minutes. However, if you rode a bicycle, you could get home in 10 minutes.

a) 3.33m/s b) 8.33m/s c) 15minutes faster

Explanation:

The question is incomplete. This is the complete question;

Suppose you are walking home after school. the distance from school to your home is five kilometers. on foot, you can get home in 25 minutes. however, if you rode a bicycle, you could get home in 10 minutes. what is your average speed while walking? what is your average speed while bicycling? how much faster you travel on your bicycle?

Speed is the defined as Distance covered by a body in a specified time. Mathematically;

Speed = Distance/Time

- If the distance from school to home is 5km and time taken to get home on foot is 25minutes, average speed while walking will be calculated as;

Average speed while walking = distance covered on foot/time taken on foot

Average speed while walking = 5km/25mins = 0.2km/min

Covering to m/s gives;

(0.2×1000)m/(1×60)secs

= (200/60)m/s

= 3.33m/s

- average speed while bicycling = distance covered on bicycle/time taken on bicycle

Distance from school to home will not change i.e 5km = 5000m

Time taken on bicycle home = 10mins = 10×60 = 600seconds

average speed while bicycling = 5000/600

average speed while bicycling = 8.33m/s

- to calculate how much faster traveled by bicycle, we will subtract time taken on foot from time taken by bicycle to have;

25min - 10mins

= 15minutes

This means he travels 15minutes faster on bicycle compare to foot
