Answer 2

Given,

The maximum speed attained by a sprinter = 10 m/s

To find,

The speed attained by the sprinter in Km/hr.

Solution,

We can simply solve this mathematical problem using the following process:

Mathematically, according to the units of conversion;

1 Km = 1000 m

=> 1 m = 1/1000 Km

=> 10 m = 1/100 Km

And, 1 hr = 3600 s

=> 1 s = 1/3600 hr

{Statement-1}

Now, according to the question;

The maximum speed attained by a sprinter

= 10 m/s

= (10 m)/(1 s)

= (1/100 Km)/(1/3600 hr)

{according to statement-1}

= (1/100)×3600 Km/hr

= 36 Km/hr

Hence, the maximum speed attained by the sprinter is equal to 36 Km/hr.
