I don't understand how to solve this.

I only know how to solve it if the problem has the velocity for both.

Please could someone write the equation

**Dr Russ**, Thursday, September 16, 2010 at 4:25amlet A = speed of Amtrak train

let M=speed of Metro train

so we can write A=M+50

as A is travelling 50 mph faster than M

as there are two unknowns we need another equation

at 3pm distance travelled by A is Ax1 or 1A miles

at 3pm distance travelled by M is Mx3 miles

but A is 10 miles behind M so

3M-10=1A

we now have two equations so we can solve these for A and M.
