Two Trucks leave the same intersection one traveling East at 45 mph and the other traveling North at 60 mph. At what rate is the distance between them changing at 2 pm if they both leave at noon? If the north bound leaves at noon and east bound at 1 pm.?

The eastbound truck is at P(45t,0)
The northbound truck is at P(0,60t)
They form a right triangle so the distance between them is
D = sqrt((45t)^2+60t)^2)
find dD/dt at t=2
The eastbound truck is at P(45(t-1),0)
The northbound truck is at P(0,60t)
Same problem
I assume you needed help with the equations, not the derivitives.
