Question

Rashmi goes to school at 4 km/h in 2 h 30 min. How much time will she cover in 25 min​

Answer 1

As speed = DIST / TIME

Let x be the time of her school so by equation

4kmph = DIST / (x+5)

I.e 4(x+5) = d …….(1)

As she was late 5 mins hence x+5

For 2nd case

6 KMPH= DIST / (x-10)

I.e 6(x-10)=d……(2)

As LHS are equal , hence

4(x+5)=6(x-10)

4x+20=6x-60

80=2x

X= 40
