Answer: 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.
