11. Jim travelled at a speed of 18km/h for 2 hours. What was the distance covered?

Igoryamba

Answer:

d = 36 km

Step-by-step explanation:

Speed of Jim, v = 18 km/h

Time, t = 2 hours

We need to find the distance covered. We know that the speed of an object is equal to the distance covered by it divided by total time taken.

$v=\dfrac{d}{t}\\\\d=v\times t\\\\d=18\ km/h\times 2\ h\\\\=36\ km$

So, he will cover 36 km.
