Answer 2

#### Problem Analysis We are given that two minibuses start from Brest and Minsk simultaneously. The speed of the first minibus is 85.7 km/h, and the second minibus travels 4.58 km more than the first minibus in one hour. We need to find the distance between the minibuses after 2.5 hours, given that the distance from Brest to Minsk is 348.1 km. #### Calculation To find the distance between the minibuses after 2.5 hours, we need to calculate the distance each minibus has traveled in that time. The first minibus travels at a speed of 85.7 km/h. Therefore, in 2.5 hours, it will travel: Distance of the first minibus = Speed of the first minibus * Time = 85.7 km/h * 2.5 h The second minibus travels 4.58 km more than the first minibus in one hour. Therefore, in 2.5 hours, it will travel: Distance of the second minibus = Distance of the first minibus + 4.58 km Finally, we can find the distance between the minibuses after 2.5 hours by subtracting the distance traveled by the first minibus from the distance traveled by the second minibus. #### Solution Let's calculate the distances: Distance of the first minibus = 85.7 km/h * 2.5 h = **214.25 km**. Distance of the second minibus = Distance of the first minibus + 4.58 km = 214.25 km + 4.58 km = **218.83 km**. The distance between the minibuses after 2.5 hours is the difference between the distances traveled by the second minibus and the first minibus: Distance between the minibuses = Distance of the second minibus - Distance of the first minibus = 218.83 km - 214.25 km = **4.58 km**. Therefore, the distance between the minibuses after 2.5 hours is 4.58 km. Please let me know if I can help you with anything else.
