A car and a trolley are driving in the same direction on the expressway. . .

Solution: If the speed of the cart is x km/h, then the speed of the cart is1.5xkm/h. ..

From the meaning of the title: 2* 1.5x=2*x+60.

Solution: x=60

So the speed of the cart is 60 km/h;

1.5x=90, that is, the vehicle speed is 90km/h.

The traveling distance of the cart is 60*2= 120 (km).

The driving distance of the car is 90*2= 180 (km).
