Question

a car cover a distance of 3 km in 5 minutes calculate its speed in metre per second​

Answer 1

Answer:

10 m/sec

Explanation:

3 km = 3000 m

5 min = 300 sec

speed = 3000/300

= 10 m/sec

Answer 2

Answer:

Given

distance = 3 km

time = 5 minutes

1. Speed = distance/time

              =  300000 cm/ 300 sec

              = 1000 cm/s

2. 3 km = 3000m and 5 min = 300 sec

speed = 3000/300 = 10 m/s

3. 3 km = 3 km and 5 min = 1/12 h

Now speed = 3*12/1 = 36 km/h
