a car left town A at 10:00 am and travelled towards town B at the average speed of 70 km/h. At the same time a truck left town B
Softa [21]
The important formula to this problem is distance=rate(time) or d=rt

Now, the speed of the car is 70 km/h, and the speed of the truck is 50 km/h. It will take the two vehicles the same amount of time to meet since they both left at the same time. So, since distance equals rate times time, and t = time:

the distance of the car = 70t
the distance of the truck = 50t

Because they both left in opposite directions, and the towns are 420 kilometers apart, the equation for this would be

70t+50t=420

We now solve the equation.

70t+50t=420 \\ 120t=420 \\  \frac{120t}{120}= \frac{420}{120}  \\ t=3 \frac{1}{2}

It will take the vehicles 3 and a half hours to meet. Since we're looking for the time, 3 and a half hours from 10:00 AM is 1:30 PM.

So, the car and the truck will pass each other at 1:30 PM.
