Question

A jet airways travels 72000 km in one hour. Express its speed in km/s.

Answer 1

Answer:

20km/s

Explanation:

Speed Given = 72000km/hr

To find km/s

We know that 1hr = 3600 seconds

So, 72000 km / 1hr

= 72000 km / 3600 seconds

By reducing the fraction, we get

72000 km / hr = 20 km / second

Hence, the speed will be 20 km/s
