Answer: the faster train is travelling at 63.7 mph
The slower train is travelling as 45 mph
Step-by-step explanation:
Distance = speed × time
Speed = distance/time
The two trains leave Tucson at the same time. In 6 hours, the faster train is 382 miles from Tucson. This means that the speed at which the faster train is travelling is
382/6 = 63.7mph
In 6 hours, both trains are 112 miles apart. This means that the distance covered by the slower train in 6 hours is
382 - 112 = 270 miles
Therefore, the speed at which the slower train is travelling is
270/6 = 45 mph
