Question 665437: Tory and Emilio's motorboats travel at the same speed. Tory pilots her boat 40 km before docking. Emilio continues for another 2 hr, traveling a total of 100 km before docking. How long did it take Tory to navigate the 40 km?
So far I've got this, but I don't think it's right and don't know how to proceed in any case
Distance = Rate * Time
Tory 40km r t
Emilio 100km r t+2

Tory pilots her boat 40 km before docking. Emilio continues for another 2 hr, traveling a total of 100 km before docking. How long did it take Tory to navigate the 40 km?
Let their speeds = x km/h
time taken by tory = 40/x hours to dock
Emilio pilots for another 2 hours = (40/x)+2) hours
Emilio pilots 100 km for (40/x)+2) hours
d/t=r
100/ (40/x) +2) =x
100 = x(40/x) +2)
100= 40+2x
2x= 60
x= 30
Tory takes 40 /30 = 4/3 hours for 40 km.
