Question

8. Express the following speeds in metres per second:
(a) 36 km per hour (b) 60 km per hour (c) 126 km per hour​

Answer 1

Answer:

Formula : Divide the speed value by 3.6.

a) 36 km per hour = 36÷3.6 = 10 m per second.

b) 60 km per hour = 60÷3.6 = 16.6667 m per second.

c) 126 km per hour = 126÷3.6 = 35 m per second.

Hope it helps! :)

Answer 2

Answer:

The conversion from kilometers per hour to meters per second is as follows:

(a) 36 km per hour = 36 ÷ 3.6 = 10 meter per second.

(b) 60 km per hour = 60 ÷ 3.6 = 16.6667 meter per second.

(c) 126 km per hour​ = 126 ÷ 3.6 = 35 meter per second.

Explanation:

We have relationships between Kilometers(cm) and meters(m);

We have relationships between hours and seconds;

That means;

1 km = 1000 m;

1 hour = 3600 seconds;

So, Let us first convert and find the relationship between

1 km/hr into 1 m/s.

So, 1 m/sec = 3.6 km/hr;

So, In order to convert speed from meters per second to kilometers per hour, we have to just multiply it by 3.6.

and

In order to convert speed from kilometers per hour to meters per second, we have to just divide it by 3.6.

So,

(a) 36 km per hour = 36 ÷ 3.6 = 10 meter per second.

(b) 60 km per hour = 60 ÷ 3.6 = 16.6667 meter per second.

(c) 126 km per hour​ = 126 ÷ 3.6 = 35 meter per second.
