Question

two trains started their journey from a station, one towards east and other towards north the speed of first train five more than that of other. distance between them after 2 hour will be 50km find the speed of train
​

Answer 1

Answer:

Let the average spped of the second train be x km/h.

Thus, the speed of the first train will be (x+5) km/h.

Distance travelled by the first train in two hours =2(x+5) km/h

Distance travelled by the second train in two hours =2x km/h

Using pythagoras theorem, we have

4x^2+4(x+5)^2

=50^2

4x^2+4x^2+40x+100

=2500

8x^2+40x−2400

=0

x^2+5x−300

=0

(x−15)(x+20)=0

x=15,−20

Ignore the negative value of the speed. We have,

Speed of the second train be 15 km/h.

Speed of the first train be (15+5)= 20 km/h.

I hope it helps you out
