Question 986119
The front of the car has to be in front of the truck by at least 16 feet in 4 seconds.  That is 44 feet in 4 seconds or 11 feet per second overtaking, in addition to the 44 feet per second the truck is moving.
(60 mph=88 feet/second, and that is useful to know).
55 feet per second is 5/8 of 60 mph, or 37.5 mph.
