Get if right!! *A raft is drifting from A to B in 6 hours. A motorboat goes
from A to B in 2 hours. If the speed of the raft is 3 mph, find the
speed of the motorboat in still water.

Step-by-step explanation:

To find the the distance between A and B, use , where is distance, is rate/speed, and is time.

The raft travels from A to B in 6 hours at a rate of 3 mph. Thus, the distance from A to B must be:

miles.

Since the motorboat travels the same distance in 2 hours, its rate/speed must be:

Because the raft is drifting, the speed of the current must be in the direction of the raft (from A to B). Thus, let the motorboat's speed be :

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
