Answer 1

1) 95*3=285
2) 537-285= 252
3) 252:3=84 км/ч
Ответ 84 км/ч

Answer 2

Именно как выше человек сказал, не благодарите

Answer 3

#### Problem Analysis We have a train and a commuter train (electric train) that depart simultaneously from the same station in opposite directions. The speed of the train is given as 95 km/h. After 3 hours, the distance between them is 537 km. We need to find the speed of the commuter train. #### Solution Let's assume the speed of the commuter train is **x** km/h. After 3 hours, the train will have traveled a distance of 95 km/h * 3 h = 285 km. The commuter train will have traveled a distance of **x** km/h * 3 h = 3x km. The total distance between the train and the commuter train after 3 hours is 537 km. Therefore, we can write the equation: 285 km + 3x km = 537 km To find the speed of the commuter train, we need to solve this equation. #### Solving the Equation Let's solve the equation step by step: 285 km + 3x km = 537 km Subtract 285 km from both sides of the equation: 3x km = 537 km - 285 km 3x km = 252 km Divide both sides of the equation by 3: x km = 252 km / 3 x km = 84 km/h #### Answer The speed of the commuter train is **84 km/h**. #### Verification Let's verify our answer using the given information. After 3 hours, the train will have traveled a distance of 95 km/h * 3 h = 285 km. The commuter train will have traveled a distance of 84 km/h * 3 h = 252 km. The total distance between the train and the commuter train after 3 hours is 285 km + 252 km = 537 km, which matches the given information. Therefore, our answer is verified.
