Question

22. The time taken by Arushi to cover 150 km was 2 hrs 30 minutes more than the time
taken in return journey. If she returned at a speed of 10 km/hr more than the speed
of going, find her speed in each direction.​

Answer 1

Answer:

20 km/h

converting 30min into hrs

we get,

2hr 30 mins

2+ 30/60

2+1/2

2.5hrs

speed= distance/time

150/2.5= 70km/h

he say if she run 10 km /h more faster

then 70+10=80km/h

so,

speed in each direction,

as we know there are four direction

therefore,

80/4=20km/h

so, her speed in each direction is 20km / h
