A row team paddles 30 miles upstream in 2 hours and 30 miles downstream in 45 minutes. How fast can the row team paddle in still

sp2606 [1]

Answer:

Rate in still water = 27.5 mph

Current's rate = 12.5 mph

Step-by-step explanation:

Let

x mph = row team rate in still water

y mph = current's rate

<u>Upstream:</u>

Distance = 30 miles

Time = 2 hours

Rate = x - y mph

Then

$30=2(x-y)$

<u>Downstream:</u>

Distance = 30 miles

Time = 45 minutes $=\dfrac{3}{4}$ hour

Rate = x + y mph

Then

$30=\dfrac{3}{4}(x+y)$

From the first equation:

$30=2(x-y)\Rightarrow 15=x-y$

From the second equation:

$30=\dfrac{3}{4}(x+y)\Rightarrow 40=x+y$

Add these two equations:

$15+40=x-y+x+y\\ \\2x=55\\ \\x=27.5\ mph$

Subtract these two equations:

$40-15=x+y-(x-y)\\ \\25=x+y-x+y\\ \\2y=25\\ \\y=12.5\ mph$

Answer:

Step-by-step explanation:

To solve this, you need to find the unit price by dividing the cost by the amount. For Mike, divide $2 by 2 to get 1. So, Mike sells hot dogs for $1. Next, divide 2.25 by 3 to get $0.75. So, Sue sells hot dogs for $0.75.

Joe: $1.50

Mike: $1

Jen: $1.25

Sue: $0.75

So, the best deal is Sue because it is the cheapest per unit. Hope this helped!
