Question

A car is moving at the speed of 54 km/h .What is the Speed in meter per second.

Step by Step ​

Answer 1

Answer:

The car is moving at a speed of 54 km/h. Means

We know 1 hour = 60 × 60 seconds = 3600 seconds

1 kilometer = 1000 meters

54 kilometer = 54 × 1000 = 54000 meters

Car moves in 3600 seconds, the distance of 54000 meters

Car is covering distance in 1 second = 54000/3600 = 15 meters

Thus in first one second car will cover 15 meters

In next second, the speed is 63 km/h.

1 kilometer = 1000 meters

63 kilometer = 63 × 1000 = 63000 meters

Car speed = 63000 meters / 3600 second

Car moves in 3600 seconds as 63000 meters

Car moves in 1 second = 63000/3600 = 17.5 meters

Thus in next one second car will cover distance of 17.5 meters

In first 1 second, when car speed is 54 km/hour car is covering distance of 15 meters, in next one second, when car speed is 63 km/hour, the car is covering dustance of 17.5 meters
