Two trains travel at right angles to each other after leaving the same train station at the same time. Two hours later they are

hjlf

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

$x^2+y^2=\left ( 4420\right )^2$

$\left ( 2v\right )^2+\left ( 2\left ( v+29\right )\right )^2=\left ( 4420\right )$

on solving

$2v^2+58v-4881699=0$

v= $\frac{-58\pm \sqrt{\left ( 58 \right )^2+4\cdot 2\cdot4881699}}{2\cdot 2}$

v=1547.889 miles per hour
