Question

A train takes 5 hours to complete a journey at a speed of 108 km/h .How long will another train take to complete the same journey if its speed is 15 m/s

Answer 1

Answer:

10 hrs

Step-by-step explanation:

Distance=Speed*time

A train takes 5 hours to complete a journey at a speed of 108 km/h .

Distance=5*108

How long will another train take to complete the same journey if its speed is 15 m/s

let x be time to take

Speed is 15 m/s convert to km/hr

  15*18/5=54 km/hr

Distance=54*x

if distance is same then

5*108=x*54

x=10 hrs
