Question

A cyclist is travelling at an average speed of 24km/h.

1. How long does it take him to travel 2km?
2. How far does he travel in 20 seconds?​

Answer 1

The answer is: 1. 5 minutes and 2. 133.3 meters

Explanation:

To find how long it takes the cyclist to travel 2km at 24km / hour, set up the equation and cross multiply:

2 / 24 = x / 1

24x = 2

x = 2/24 = 1/12 of an hour or 60 / 12 = 5 Minutes.

To find how far he travels in 20 seconds:

Multiply 24 km by 1000 to get meters per hour. Divide by 3600 to get meters per second:

24000 / 3600 = 6.6 meters per second.

Multiply by 20 seconds to get the distance traveled in 20 seconds:

6.6 * 20 = 133.3
