Question

What will be the speed of boy in m/s and km/hr if it travels 40 kms in 5hrs? ​

Answer 1

Answer:

We know that ,

1 km = 1000 m and 1 hour = 3600 second

So, 1 km/h = 1000/3600 m/s = 5/18 m/s.

Now,

Speed in km/h —

Speed = 40/5 = 8 km/h.

2. Speed in m/s —

1 km/h = 5/18 m/s.

Therefore,8 km/h = 8 *5/18 m/s = 2.22 m/s

So, the speed in km/h is 8 km/h and in m/s is 2.22 m/s.

Step-by-step explanation:

Hope you got your answer !!!!! :)

Answer 2

Answer:

We know that ,

1 km = 1000 m and 1 hour = 3600 second

So,

1 km/h = 1000/3600 m/s = 5/18 m/s.

Now,

Speed in km/h —

Speed = 40/5 = 8 km/h.

2. Speed in m/s —  

1 km/h = 5/18 m/s.  

Therefore,8 km/h = 8 *5/18 m/s = 2.22 m/s  

So, the speed in km/h is 8 km/h and in m/s is 2.22 m/s.
