A truck and a car leave a service station at the same time and travel in the same direction. The truck travels at 52 mph and the car at 44 mph. They can maintain radio contact within a range of 12 miles. When will they lose contact?

Respuesta :

Answer:

After 1.5 hours

Step-by-step explanation:

The truck and the car are moving in the same direction after they left the service station at the same time. The truck travels at 52 miles per hour and the car at 44 miles per hour.

Let us assume that after h hours their distance from each other will be 12 miles.

So, 52h - 44h = 12

⇒ 8h = 12

⇒ h = 1.5 hours.

Therefore, after 1.5 hours their distance from each other will be more than 12 miles and their radio contact will be lost after that. (Answer)
