Question

A tractor is moving with a velocity of 500 cm/s calculate its value in km/h

Answer 1

First convert speed given in cm/s to m/s.
i.e. 1 m = 100 cm
therefore speed of tractor is 5 m/s.

now converting m/s to km/hr
 1 hour = 3600 seconds
 so 1 second = 1/3600 hour
 
 1 km = 1000 m
so 1 m = 1/1000 km
now 5 m/s = $5* \frac{1}{1000}/ \frac{1}{3600}$
i.e speed of tractor is 18 km/hr

Answer 2

Answer:

The final answer is 18KM/H

Explanation:

To get the speed in KM/H need to convert the given data in the km and hours and then multiply it with the original value

Given: A tractor is moving with a velocity of 500 cm/s

To find The value in km/h.

Calculation:

Convert speed in m/s.

500 cm/s=500*1/100 m/s

=5m/s

Convert km/hr

In 1 ms there is 1/3600 hour

So,

If the value of the 1km is 1000m. Then the value of 1m is

1m=1/1000km

Then for the 5m/s

$5ms=5*(\frac{1}{1000} /\frac{1}{3600} )\\=$

The final answer is 18KM/H
