Question

A train covers 405 / 5 km in 1 hour . how much distance it cover in 19/4 hours
​

Answer 1

Answer:

hey dear

here is your answer

given data : time = 1 hour & distance = 404/5

speed = distance / time = 404/5×1 = 80.8 km/hr

so, in 19/4 hours it will cover distance,

distance = speed × time = 80.8×19/4 = 383.8 km

Step-by-step explanation:

Answer 2

Answer:

Distance a train covers in one hour = 405 ÷ 5 = 81 km per hour

Distance to be covered by the train = 19 ÷ 4 = 4.75 hour

Therefore , distance covered by the train = ( 81 × 4 ) + ( 81 × 0.75 ) = 324 km + 81 × 0.75 km =

324 km + 60.75 km = 384.75 time

Therefore , at the speed of 81 km / hour the train took 384.75 time for covering 4.75 km .
