Question

1)If a train travels 437 kilometers in 6 hours 35 minutes ,how much time will it take to cover 500 kilometers?
2)If the train travels 20 KMPH faster than the original speed, how much time will it require to travel 437 kilometers?
3) By what percentage did the train's speed increase in the second case?​

Answer 1

Answer:

1)

6hrs 35 min=395min

435=395

500=x

cross multiply

2)

originL speed = 437/6.58

new speed=437/6.58 + 20

time = dist /time
