Answer 1

Answer:

The total time taken by him in forward journey is 3 hrs.

The total time taken by him in return journey is 2.5 hrs or 2 hrs 30 minutes.

Step-by-step explanation:

Let speed = X

Time = distance/ speed

Time taken in forward journey= 150/X

Time taken in return journey= 150/X+10

by given condition

$\frac{150}{x} - \frac{150}{x + 10} = \frac{30}{60}$

since, 30 minutes= 30/60 hrs

when you solve this you get

the value of x = 50,

i.e speed = 50 km/hr

Time taken in forward journey= 150/50 = 3 hrs

Time taken in return journey= 150/ 50+10 = 2.5 hr
