Acar and a bus which are 280 miles apart are driving towards each other. the car is moving at 50 mph while the bus is moving at 55 mph. how long will it take them to meet?

2 2/3 hours or 2 hours 40 minutes

Step-by-step explanation:

Bus = 55 mph

Car = 50 mph

Distance apart = 280

First, we add up their speeds:

55+50 = 105 mph

This tells us how fast they are moving closer together.

Then we take the total distance and divide by this speed to get the time before they meet, because Distance/speed = time

So:

280/105 = 2 70/105

The fraction 2 70/105 can be reduced to 2 2/3.

So, the time before the car and the bus meet is 2 2/3 hours, or 2 hours 40 minutes.
