Two trains depart the station traveling in different directions. Their paths are at a 90-degree angle from one another, as shown in the following illustration. train 1 train 2 Train 1 leaves the station traveling at 50 mph. Train 2 leaves the station one hour later traveling at 75 mph. Assuming that t represents the time that train 1 has been in route, which of the following inequalities can be used to calculate the values oft for which the distance between the trains is greater than or equal to 100 miles?
