35x + 25x = 150
______________
60x= 150
_________
= 2.5
35(2.5) = 87.5 KM/H
25(2.5) = 62.5 KM/H
Hope I did this right.
Help guys!! I have no clue where to start this problem. Any help would be appreciated
This is the problem.......
At noon, ship A is 150 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 25 km/h. How
fast is the distance between the ships changing at 4:00pm?

distance equation
x = square root of ((150-35t)square + (25t)square)
dx/dt = rate of distance relative to time
differentiate the other side
and plug in 4 as time
you will get 21.3933
