A man covers a distance of 600 m in 2 min. 30 sec. What will be the speed in km/h?
Answers
Answer:
14.4 km/hr
Step-by-step explanation:
600 m in 2min30sec ,i.e. 600 m in 150 seconds.
In 1 second he covers 600/150= 4 meters.
So, his speed is 4m/s
To convert meter/second into km/hr, multiply this value by 18/5 or 3.6.
4 * 18/5 = 14.4.
So the speed of the man is 14.4 km/hr.

Given:
A man covers a distance of 600m in 2 min. 30 sec.
To find:
The speed of the man in km/h
Solution:
The speed of the man is 14.4 km/hr.
To answer this question, we will follow the following steps:
First of all, we should know that if an object travels or covers distance 'd' in time 't' then its speed is given by:
Now,
proceeding to the solution, we have
Distance covered by man
(as 1 km = 1000 m)
The time that was taken by the man to cover 600m distance = 2 min. 30 sec.
(as 1 hour = 60 minutes = 60 × 60 sec = 3600 seconds)
So,
Speed of the man in km/hr
Hence, the speed of the man is 14.4 km/hr.
