Question

The distance between two cities is 380 km . A train takes 6 hours 40 min to cover the distance . Find the speed of the train.​

Answer 1

distance=380km

time=6hour and 40 min

= 6+2/3h

speed = 380/6+2/3

380/20/3

380/20 *3

57 km/h

Answer 2

Answer:

57 km per hour

Explanation:

$Distance \: travelled \: by \: train \: = 380 \: km \\ </p><p>Time \: taken = 6 hours \: 40 minutes = 6 \frac{40}{60} = 6 \frac{2}{3} = \frac{20}{3} hour \\ speed \: = \frac{distance}{time} \\ = \frac{380}{ \frac{20}{3} } = 380 \times \frac{3}{20} \\ = 19 \times 3 \\ = 57km \: per \: hour$
