a body stars with a speed of 50 km/h and after travelling for 30 minutes it attended the speed of 100km/h now calculate average speed of the body

the change in velocity of a body in 30km/sec in 60 minute calculate the acceleration

a body travels with initial velocity of 10km/sec after 30 minutes it came to rest .then calculate the acceleration of the body
