A boat moves at a rate of 10 mph in still water. if the rivers current flows at a rate of 2 mph, how long does it take the boat to travel 28 miles?

B is rate of boat=10 mph

W is rate of river/water=3 mph

(B-W)Tu=D <--equation for traveling upstream

(10-3)Tu=32

7Tu=32

Tu=32/7 hrs or 4.6 hrs

Additional notes:

If you were traveling downstream, your equation would look like this: (B+W)Td=D

Step-by-step explanation:

Hopes it helps

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
