Question

a racing car covers 600 km in 3 hours 20 minutes find its speed in metre per second how much distance will the car cover in 50 second

Answer 1

Distance =600000m
Time=200 minute=200*60=12000 sec
speed=600000/12000
=50 m/sec
distance in 50 sec= 50*50=2500 m

Answer 2

Its speed is 50  m/sec .The car cover 2500 m in 50 second

Step-by-step explanation:

Distance covered = 600 km

1 km = 1000 m

600 km = $1000 \times 600 = 600000 m$

Distance covered = 600 km = 600000 m

Time taken = 3 hours 20 minutes

1 hour = 3600 seconds

3 hours = $3 \times 3600 = 10800 seconds$

1 minute = 60 seconds

20 minutes = $20 \times 60 =1200 seconds$

Time taken = 3 hours 20 minutes = 10800+1200=12000  seconds

$Speed = \frac{Distance}{Time}$

$Speed = \frac{600000}{12000}=50 m /sec$

Distance covered in 12000 seconds = 600000 m

Distance covered in 1 second =$\frac{600000}{12000}=50$

Distance covered in 50 second =$50 \times 50 = 2500 m$

Hence the car cover 2500 m in 50 second
