Answer 1

Problem Analysis

To solve this problem, we need to find the distance between city A and city B. We are given that a train leaves city A with a speed of 50 kilometers per hour after 12 hours. Additionally, a helicopter takes off from city A with a speed that is seven times greater than the speed of the train. The collision between the train and the helicopter occurs at the halfway point between city A and city B.

Solution

Let's break down the problem step by step:

1. Calculate the speed of the helicopter: Since the speed of the train is given as 50 kilometers per hour, the speed of the helicopter is seven times greater, which means it is 7 * 50 = 350 kilometers per hour.

2. Calculate the time it takes for the train to reach the halfway point: Since the train starts 12 hours after the helicopter, the time it takes for the train to reach the halfway point is the same as the time it takes for the helicopter to reach the halfway point. Let's call this time 't'.

3. Calculate the distance traveled by the train and the
