Ok - first of all this is a interesting problem because it is pretty challenging.
1st) Convert the miles/hr to feet/sec and acceleration to ft/sec^2. Here are examples of how to do both.
50 miles/hr x 1hr/3600 sec x 5280 ft/mile = 73 ft/sec
As soon as a traffic light turns green, a car speeds up from rest to 50.0 mi/h with constant acceleration 9.00 mi/h/s. In the adjoining bicycle lane, a cyclist speeds up from rest to 20.0 mi/h with constant acceleration 13.0 mi/h/s. Each vehicle maintains constant velocity after reaching its cruising speed. (a) For what time interval is the bicycle ahead of the car? (b) By what maximum distance does the bicycle lead the car? (1mil=1.6 km)
