If joe rides his bike for 15 minutes at 20 km/hour south, how far has he ridden? (give the answer in km) watch the units!

Distance covered by Joe, d = 5 km

Explanation:

It is given that,

Speed of Joe, v = 20 km/hour

Time taken by Joe, t = 15 minutes = 0.25 h

We need to find the distance he is covering. It can be calculated using definition of speed as :

d = 5 km

So, Joe covers a distance of 5 km. Hence, this is the required solution.
