the bus staions in trawley and fenton are 220 miles apart. a bus left at trawly for at 9;00 am traveling at 40 miles per hour .one hour later, an express bus left left fenton along the same road at 50 miles per hour. at what time did the buses pass each other

To find the time when the buses passed each other, we can set up a distance equation based on the information given.

Let's assume that the time when the buses passed each other is "t" hours after the first bus left Trawley.

Since the first bus left at 9:00 am and the second bus left Fenton one hour later, the second bus would have been on the road for t - 1 hours.

Now, let's calculate the distance covered by each bus. The distance covered by the first bus is given by:

Distance = Speed * Time
Distance = 40 * t (miles)

The distance covered by the second bus is given by:

Distance = Speed * Time
Distance = 50 * (t - 1) (miles)

According to the given information, the distance between Trawley and Fenton is 220 miles. Therefore, we can set up the distance equation:

Distance covered by the first bus + Distance covered by the second bus = Total distance between Trawley and Fenton
40 * t + 50 * (t - 1) = 220

Now, let's solve the equation:

40t + 50t - 50 = 220
90t - 50 = 220
90t = 220 + 50
90t = 270
t = 270 / 90
t = 3

So, the buses passed each other 3 hours after the first bus left Trawley.

Since the first bus left at 9:00 am, the buses passed each other at 9:00 am + 3 hours = 12:00 pm (noon).
