Question 613795
A train leaves at 10 am and is traveling 55 mph due east. Another train leaves 2 hours after the first train traveling 65 mph due east so that they can catch up to the first train. How long does it take the second train to catch up to the first train? What time does the second train catch up to the first train?
--------------------------
1st east-bound train DATA:
rate = 55 mph ; time = x hrs ; distance = 55x miles
-------------------------------------------
2nd east-bound train DATA:
rate = 65 mph ; time = x-2 hrs ; distance 65(x-2) = 65x-130 miles
-------------------------------------------
Equation:
distance = distance:
55x = 65x-130
10x = 130
x = 13 
Catchup time: 11PM
