Answer: 7
Answer:
Speed of the first train = 365 mph
Speed of the second train = 356.2 mph
Step-by-step explanation:
Let speed of First train = a
Let speed of the second train = b
The sum of the speeds of two trains is 721.2 miles per hour.
a + b = 721.2 mph
If the speed of the first train is 8.8mph faster than that of the second train
a = b + 8.8 mph
We substitute b + 8.8 mph for a
a + b = 721.2 mph
b + 8.8 mph + b = 721.2 mph
2b + 8.8 mph = 721.2 mph
2b = 721.2 mph - 8.8 mph
2b = 712.4 mph
b = 712.4 mph/2
b = 356.2 mph
a = b + 8.8 mph
a = 356.2 mph + 8.8 mph
a = 365 mph
