Answer:
displacement/time = 420/17.5 = 24
velocity/time = 24/17.5 = 1.4
Explanation:
you just need to divide the displacement which is 420m, to the time which is 17.5min. so the average speed km/min is 24. now to find the acceleration just divide the velocity which is 24km/min and the time which is 17.5 min. so the average speed in m/s is 1.4
