Question

• A train takes 6 hours to complete a journey at a speed of 72 km/h. How long will another
train take to complete the same journey if its speed is 15 m/s?
​

Answer 1

Answer:

8 hours

Step-by-step explanation:

Distance= Speed× Time

Distance= 72 km/h× 6 hours

Distance= 432 Km

15 m/s = 54 Km/h (simple conversion)

Therefore,

Time= Distance/Speed

Time= 432/54

Time= 8 hours
