Train increases from 100 km/h to 250 km/h in 5 min what is it's acceleration

Answer 1

acceleration = (change in speed)/(change in time)

Since the speed is km per hour, convert the time (5 minutes) to hours:

(5 minutes)(1/60 hour/minutes) = 5/60 = 1/12 hour

acceleration = (250 kph - 100 kph)/(1/12 h) = ______ km/h²
