Question

acar Travels at the speed of 72 km per hour how many metres will it travel in one second​

Answer 1

Answer :

1 km = 1000 m  

1 hour = 3600 sec  

Distance travelled by the car in 1 hour (60 minutes) = 72 km  

Distance travelled by the car in 1 second = 72 × 1000/3600

= 72000/3600  

=20 m/s  

Distance travelled in 1 second = 20 m    

Distance travelled in 30 seconds = 20×30  

=600 m  

So, the car travelled 600 metres in 30 seconds.
