Question

A train cover 80whole4/5km in 1 hour.How much distance will it cover is 4whole3/4 hours.​

Answer 1

1 hour = 80 whole 4/5

1 hour = 404/5 km

4 whole 3/4 hr = 404/5 * 19/4

Answer = 1919/5 km = 383 whole 4/5 km

Answer 2

80_4/5 km = 404/5 Km in 1 hour

so velocity of the train is 404/5 km.

speed = distance/time

404/5 = x/ 4_3/4

404/5 = x/(19/4)

(404/5) × (19/4) = x

x = 383.8 km

The distance covered by train in 4_3/4 hour is 383.8 km.
