A bus is moving with a speed of 90 km / hr on a straight line track. The driver applies brakes and uniformly reduces its speed from 90 km / hr to 60 km / h r in 2 mins. Calculate the average velocity of the bus during this uniformly retarded motion.

90+60= 150 kms pr hour
150kms per hour /2 minutes = 75
the average velocity if the bus during that period = 75 kms per hour
150kms per hour /2 minutes = 75
the average velocity if the bus during that period = 75 kms per hour
