Question

A person travels at a speed of 15m/s. How much distance will he cover in 20 hours?

Answer 1

Answer:

1080km

Explanation:

1 sec -----------------> 15m

20*60*60 sec ------------------------->15*20*60*60

                                                    =>1080000 m

                                                    = 1080km

Answer 2

Explanation:

speed = distance/time

= 15m X 3600mins. [1 hour = 3600 mins]

= 54000m/hr.

Now,

distance = Speed X time

= 54000m X 20hrs

= 108000m

= 1080km.
