You row a canoe x miles per hour down a river for 20 minutes. on the return trip, you travel 1 mile per hour slower. the return trip takes
30 minutes. how far did you ride the canoe in total?

Total Distance = 2 miles

Step-by-step explanation:

We know D = RT where

D is distance

R is rate (speed)

T is time

First Leg:

Rate = x mph

Time = 20/60 = 1/3 hour

Hence, D = RT, Distance = x * 1/3 = x/3 miles

Second Leg:

Rate = x - 1

Time = 30/60 = 1/2 hour

Distance = (x - 1) * 1/2 = (x-1)/2

Total distance is the sum of both the legs, hence,

Total distance = miles

Since both the distance are equal we can equate and solve:

Plugging this x = 3 into the total distance expression, we get:

Total distance, 2 miles

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

answer

you start with $5 and save $10 a week until you have at least $45wer
