We can write the position of the car at time t as
where is the speed of the car, while the position of the truck is
where
is the initial distance between the car and the truck (at 3:00 pm)
is the speed of the truck
The car overcomes the truck when they have same position, so
This occurs at 4:30 pm, so 1:30 h (1.5 h) after the initial instant. So, by using
t = 1.5 h
And solving the equation for , we find the speed of the car:
