Answer 2

☯ Time taken to travell 20km = 0.28 h

Given ,

• Speed of bus = 70 km/h

We need to find ,

• Time taken to travell 20km with a speed of 70km/h

So ,

⇒ Speed = Distance/Time

⇒ 70km/h = 20/Time

⇒ 70 × time = 20

⇒ Time = 20/70

⇒ Time = 2/7

⇒ Time = 0.28 h

Hence , time taken to travell 20km = 0.28 h
