Question

A bus travel from point p to q with the speed of 36km/hr and return with the speed of 8km/hr if total time taken in whole journey is 8:48 hours then find the distance between p and Q

Answer 1

Answer:

Step-by-step explanation:

The bus traveled let the total distance be x

Now the speed during going to the destination q was 36km/hr

And while returning was 8km/hr

So the avg speed of the bus in this whole journey was =2*36*8/(36+8)

=13.090km/hr

Now converting the speed to km/min we get,

The speed of bus =13.090/60km/min

=0.218166km/min

Now the total distance covered by bus is 2x

So distance=speed*time

2x= 0.2181666*528[where 8hr48mins = 528mins]

X=57.59600km

So the distance between p and q is 57.596km
