Answer:
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 :
[tex]v=\dfrac{d}{t}[/tex]
[tex] d=v\times t[/tex]
[tex] d=20\times 0.25[/tex]
d = 5 km
So, Joe covers a distance of 5 km. Hence, this is the required solution.
