It takes 2 hours for Ian to travel 16 miles upstream in his boat, and it takes 3 hours to travel 36 miles downstream. Which system of linear equations can be used to find the speed of the boat (b) in still water and the rate of the current (c)?

The speed of the boat (b) in still water is 10 miles/hour and the rate of the current (c) is 8 miles/hour.

Step-by-step explanation:

Given,

In upstream it takes 2 hours to travel 16 km

In downstream it takes 3 hours to travel 36 km

To find the speed of the boat (b) in still water and the rate of the current (c)

Formula

Distance = Speed × Time

According to the problem,

b-c = ------ (1)

b+c = = 12 ------- (2)

Adding (1) and (2) we get,

b-c+b+c = 8+12

or, 2b = 20

or, b = 10

Subtracting (1) from (2) we get,

b+c-b+c = 12-8

or, 2c = 4

or, c = 2

Hence,

The speed of the boat (b) in still water is 10 miles/hour and the rate of the current (c) is 8 miles/hour.

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!
