Answer:1547.9 miles per hour
Step-by-step explanation:
Let the two trains leave in x direction and y direction
Velocity of train in x direction be v
therefore velocity of train in Y direction is v+29
because one train is 29 miles per hour slower than other.
Distance travel by train in x direction is(x) v(2)
Distance travel by train in y direction is(y) 2(v+29)
distance between them after 2 hours is 4420 miles
Now using pythagoras theorem


on solving

v=
v=1547.889 miles per hour
