Answer:
Speed of faster train equals 29 mph
Explanation:
Let the speed of slower train be 'x' miles per hour and the speed of faster train be 'y' miles per hour.
Distance that slower train covers in 2 hours=
Distance that faster train covers in 2 hours=
Since they move at right angles the distance between them can be found by Pythagoras formula as
It is given that
Using this in the above equation we get
This is a quadratic equation in 'x'
Comparing with standard quadratic equation we get value of x as
Thus speed of faster train = 28.58 mph
Speed of faster train = 19 mph
