Quote: At noon sarah headed from elk city to Idabel at 60 mph. Two hours later, Joan headed from Idabel to elk city at 46 mph. If it is 332 miles from Elk city to Idabel, what time did they meet?
Let Idabel be at 0. Then Elk City is at 332.
Sarah's position is s = 60T
Joan's position is j = 332 - 45(T-2)
solving these we get
60T = 332 - 45(T-2)
105T = 422
T = 422/105 = 4.02 = 4hrs 1.14 minutes
