A cab driver picks up a customer and delivers her 2.40 km away, driving a straight route. The driver accelerates to the speed limit and, upon reaching it, begins to decelerate immediately. The magnitude of the deceleration two times the magnitude of the acceleration. Find the lengths of the acceleration and deceleration phases.(adsbygoogle = window.adsbygoogle || []).push({});

The problems is asking for:

km traveled during acceleration

km traveled during deceleration

Since it says decceleration is two times the magnitude of the acceleration I tried multiplying 2/3 times 2.4 km to give me the correct ration of distance traveled, but that didn't work. I'm not sure where to go from here because it seems like I don't have enough information here to solve it.

Thanks,

Logan
