Question

A train 350 m long crosses an electric pole in 28 sec . Find the speed of the train in km/hr​

Answer 1

Answer:

Speed= Distance / time

Given:

Distance= 350m

Time= 28 sec

Speed= 350/28= 25/2 m/sec

25/2*18/5= 5*9 km/hr= 45 km/hr

Answer 2

Answer:

$speed \: = \frac{distance}{time} \\ here \: \frac{distance = 350m}{time =28s } \\ \\ so \: \frac{350m}{28s} = 12.5 \: m |s \\ \\ converting \: into \: km \sqrt[]{}hr \: \: = \\ \\ \frac{12.5 \times 3600}{1000 \times 10 = 45 \: km \: per \: hour \: } \\ \\ \\ \\ \\ if \: it \: helped \\ \: then \: plese \: \\ mark \: it \: as \\ \\ \beta rainliest \\ \\ \beta \alpha \beta \gamma e$
