Question

A man covers a distance of 100 kms in 4 hours.How much time will he take to cover a distance of 175kms?

Answer 1

distance=100 km

time=4 hr

velocity=distance/time

=100/4

=25 km/hr

new distance=175 km

time=distance/speed

=175/25

=7 hr

Hope this helps

Answer 2

Answer:

The time taken by the man to cover a distance of 175 km is 7 hours.

Explanation:

Using the concept of distance, speed, time relationship.

• Speed is the distance traveled by an object in unit time. It has units of m/s or cm/s or km/h or mph etc.
• Speed is calculated as ratio of distance traveled to the time taken.

Given, a man covers a distance of 100 km in 4 hours.

So the speed of the man is,

Speed = $\frac{Distance}{time}$

Speed = 100/4

Speed of the man = 25 kmph

To calculate the time taken by the man to cover a distance of 175 km.

Time = $\frac{Distance}{Speed}$

Time = 175/25

Time = 7 hrs

Therefore, the time taken by the man to cover a distance of 175 km at 25 km/h speed is 7 hours.
