Question

waking at the rate of 4kmps, jhon covers a certain distance in 2 hours, calculate the distance traveling hours

Answer 1

Answer: We have been given speed=4km\h

Time=2hrs

So, distance= speed×time

Distance = 4×2

= 8km

Answer 2

Hello Friend

Here is your answer

Speed of Jhon = 4 km/Sec


Time = 2 hrs

For our calcuation we have to make both units same

So,

As 1 hrs = 60 × 60 second
= 3600 seconds

so 1 Second = 1/3600 hrs

Hence,

Speed =
$= \frac{4}{ \frac{1}{3600} } \\ \\ = 4 \times 3600 \\ = 14400 \: km \: per \: hrs$


Now We know the formula

Distance = Speed × Time
$= 14400 \times 2 \\ = 28800 \: km$
Therefore Distance is 28800 km.

Hope it helps
