A car was travelling at a speed of 25m/s northbound on the 15fwy. Suddenly the driver sees that the onramp to the 215 fwy eastbound was approaching and the driver was afraid they may miss the onramp. The driver accelerates for 5 seconds to a speed of 30m/s to change lanes so they would not miss the onramp to the 215fwy. What was the rate of acceleration when the driver was changing lanes to not miss the onramp to the 215fwy? Explain how you found your answer and include units.
