Question

Ram travels distance x with uniform velocity u and thereafter, distance y with uniform
velocity v in the same direction.
(a) What is his average speed?
(b) If he travels 1/4 of the journey with speed 40 m/s and 3/4 of the journey with speed
60 m/s along a straight line path, what is the average speed of Ram during the entire
journey?

Answer 1

Answer:

Average speed =distance covered/time

Distance covered =X+y

Time=x/u+y/v

Avg velocity =x+y/x/u+y/v

2.let the total distance is s then time taken is s/4*40+3s/4*60=160/3m/s
