Question

solve the following questions​

Answer 1

Let the speed of train = x m/sec

length of train =x × 10 =10x

now acc. to ques ,train crosses a platform in 14 secs

hence,speed of train=

x=(10x+5)/14

14x=10x+50

4x=50

x=50/4 ×18/5

=45kmph

Answer 2

Let the speed of the train =X m/sec

length of the train =X=10x+50/14

14x=10x+50

= 4x= 50

X=50/4×18/5

X=45km/h
