Question

1 km how many miter ,1 hour how many second, 72 km = how many miter, 1 min how many second ​

Answer 1

Answer:

Explanation: n the question we are given a car which is moving with a speed of 72 km/h.

We are asked to calculate the car’s speed in m/s.

We know that 1 kilometer is 1000 m.

Hence to convert kilometers into meters we need to multiply the value in kilometers with 1000.

We also know that 1 hour is 60 minutes and 60 minutes is 60×60=3600sec. Hence to convert hour to meter we need to multiply the value in hour with 3600.

Therefore to convert km/h into m/s we need to multiply the value in km/h with 10003600.

Thus in this case we have the speed of the car as, 72 km/h.

Therefore to calculate the speed in m/s we need to multiply 72 km/h with 10003600.

i.e. 72km/h=72×10003600

⇒72km/h=20m/s.

Hence the speed of the car in m/s is 20.
