Answer: they are 38 miles apart.
Step-by-step explanation:
Distance = speed × time
At 8:00 A.M., a train leaves a station and travels at a rate of 49 mph. At 10:00 A.M, the total time spent by the train is 10 - 8 = 2 hour.
Distance covered by the train is
49 × 2 = 98 miles
At 9:00 A.M., a second train leaves the same station on the same track and travels in the direction of the first train at 60 mph. At 10:00 A.M, the total time spent by the other train is 10 - 9 = 1 hour.
Distance covered by the second train is
60 × 1 = 60 miles
Therefore, their distance apart is
98 - 60 = 38 miles
