Question

A train covers a distance of 51 kilometre in 45 minutes how long will take to cover 204 kilometre

Answer 1

Answer:

180 minutes, i.e. 3 hours

Step-by-step explanation:

distance d=51 kms, t=45 min

• so, speed v=d/t=51/45 km/min

Now, distance is given 204 km

Therefore, time taken t=distance/speed=204/(51/45)=4×45

t=180 min

Answer 2

204÷51=4

45×4=180

so the answer is 180 min
