-----------------------------
Car x at 72 mph travels 2 miles in 100 seconds, so car y has to get to the same point in 100 seconds.
No info is given as to the acceleration of car y, so we'll assume it accelerates uniformly over the 2 miles, or 100 seconds. If that assumption is not valid, more info must be provided.
----------------
Car y goes 2 miles in 100 seconds, 10560 feet in 100 seconds.
Its average speed is 105.6 ft/sec. Since it starts at zero, its speed at the end of 2 miles is twice that, = 211.2 feet/second.
211.2 fps = 144 mph.
-------------------
This is not a well posed problem, too much is left to assumption.
