A certain car is capable of accelerating at a rate of +0.50 m/s2. How long does it take for this car to go from a speed of 45 mi/h to a speed of 85 mi/h?

• physics -

acceleration= (final velocity - initial velocity)/time

acceleration = .50 m/s^2
final velocity = 85 mi/h
initial velocity = 45 mi/h

be sure to convert mi/h to m/s!
