Question 888448: Two trains left the same station at the same time. One was traveling due north at a speed that was 10 kph faster than the other train, which was traveling due east. After one hour, the trains were 71 km apart. How fast to the nearest km per hour was each train traveling?

My first trial was:

.........|''\
x+10|''''\71 km
.........|'''''\
.........|----\
x
But that didn't help me...
It was supposed to be solved using quadratic equations
