two trains depart the station in different directions. their paths are at a 90-degree angle from one another, as shown in the fo
llowing illustration. Train 1 leaves the station traveling at 50 mph. Train 2 leaves the station one hour later traveling at 75 mph. Assuming the t represents the time that train 1 had been in route, which of the following inequalities can be used to calculate the values of t for which the distance between the trains is greater than or equal to 100 miles?
Open dots represent everything leading up to a number, but do not include the number itself, and closed dots include the number. Therefore, it would need to be B.
