Answer 1

Correct Question:

How many hours would a train take to cover a distance of 408 Kilometres, if it  runs at an uniform speed of 17 Kilometres an hour?

Your Answer:

Given:-

• Speed of train = 17km/h
• Total distance = 408km

To find:-

• The hours needed by train to complete the the journey

Solution:-

We know,

$\tt \blue{Total\:Time = \dfrac{Total \:Distance}{Speed}}$

So, replacing values from above to find the total time.

$\tt Total \:\:Time =\dfrac{408}{17} \\\\ \tt \Rightarrow Total\:\: Time=\cancel{\dfrac{408}{17}} \\\\ \tt \Rightarrow Total \:\: Time= 24hours$

So, the time taken by train to cover 408 km at a uniform speed of 17km/h is 24 hours.
