Question

A train leaves Little​ Rock, Arkansas, and travels north at 55 kilometers per hour. Another train leaves at the same time and travels south at 55 kilometers per hour. How long will it take before they are 330 kilometers​ apart?

GPT 3.5 · Answer

The two trains are traveling in opposite directions, so their velocities are added together: 55 km/h + 55 km/h = 110 km/h.

The distance between the two trains is decreasing by this combined speed: 330 km.

To find the time it takes for the trains to be 330 km apart, we can use the formula: time = distance / speed.

time = 330 km / 110 km/h = 3 hours.

Therefore, it will take 3 hours before the two trains are 330 kilometers apart.
