Question

Express 100 m/s in km/h
Step by step explanation is needed
Sorry for being rude..

Answer 1

Answer:

360km/hr

Explanation:

So we have to convert meters per second to k/h

So remember if we are converting lower value to higher ones then division is used .

ex:- 1m to km m<km

we know 1 km = 1000m

so 1m/1000m = 0.001km

And if we are converting higher values to lower ones then multiplication is used.

ex:- 1m to cm m>cm

we know 1 m = 100cm

so 1 × 100 = 100cm

Here , we have given lower to higher value ,

we know 100 meters is 100/1000 = 0.1km

and 1 sec is 1/60 sec × 60 min = 1/3600

so

$\frac{100m}{sec} = \frac{100}{sec} \times \frac{1}{1000}$

then putting sec formula

$100 \times \frac{1}{1000} \times \frac{3600}{1} = 360km \: perhr$

answer 360km/hr
