Question 387603: A train leaves Toronto for Montreal at the same time as another train leaves Montreal for Toronto. The cities are 500km apart. The trains pass each other 2h later. The train from Montreal is traveling 50km/h faster than the one from Toronto. At what distance away from Toronto do the trains pass each other?
I do not understand as to how I should set up each equation. Solving is easy, but setting up the equations is hard.
What I know:
Toronto Montreal
D=500km D=500km
S=x S=x+50

Question 389640: Ok...I think I might be confusing myself (lol)...so I just want to check this out with you all...
"An airplane is traveling due west at 1240ft/sec and Santa's sleigh is traveling due east at 5450ft/sec...
A. If Rudolf can spot airplanes 10,000ft ahead of him and Santa's sleigh and an airplane are 25,000ft away from each other, how many seconds will it take Rudolf to spot the airplane?"
I'm not sure if I need to add both rates together and then divide the distance (either 25,000ft...10,000ft ...or 15,000ft (25,000-10,000ft)) by both rates and then figure out the time that way...?
And...
B. If Santa's sleigh needs 2500ft to turn out of the way of another aircraft, how long does Rudolf have to inform Santa and turn the sleigh if he spots the aircraft when it is 10,000ft away?
Same problem...I'm not sure if I'm setting up this problem right...
Is it 10,000-2500= 7500/(5450+1240)=1.12 sec...?
Thanks for your help! *smiles*
