Amotorboat travels 9 miles downstream (with the current) in 30 minutes. the return trip upstream (against the current) takes 90 minutes.

which system of equations can be used to find x, the speed of the boat in miles per hour, and y, the speed of the current in miles per hour? recall the formula d = rt.

9 = 0.5(x _ y)
9 = 1.5(x + y)

9 = 1.5(x _ y)
9 = 0.5(x + y)

0.5 = 9(x _ y)
1.5 = 9(x + y)

1.5 = 9(x _ y)
0.5 = 9(x + y)

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
