Fran swims at a speed of 2.8 mph in still water. The Lazy River flows at a speed of 0.6 mph. How long will it take Fran to swim

kati45 [8]

Answer:

1. Upstream Time: 1 hour (or 60 minutes)

2. Downstream Time: 0.65 hour (or 39 minutes)

Step-by-step explanation:

The time it will take goes by the distance formula:

$D=RT$ , where D is the distance, R is the rate (speed), and T is the time.

For Upstream, you are going <em>against</em> the current, so your still water speed slows down. So upstream rate is still water rate - stream rate. So 2.8 - 0.6 = 2.2mph

Time it will take him to swim 2.2 miles, is:

$D=RT\\2.2=2.2(T)\\T=\frac{2.2}{2.2}=1$

So, 1 hour

For Downstream, you are going <em>with</em> the current, so your still water speed increases. So downstream rate is still water rate + stream rate. So 2.8 + 0.6 = 3.4 mph

Time it will take him to swim 2.2 miles, is:

$D=RT\\2.2=3.4(T)\\T=\frac{2.2}{3.4}=0.65$

So, 0.65 hours (or 0.65*60=39 minutes)

Erica chops wood in the forest. The table compares the number of cans of insect repellent Erica uses and the number of mosquito

Marina86 [1]

Answer:

Step-by-step explanation:

Step-by-step explanation:

Let x represents the number of cans of repellent and y represents the number of mosquitos,

If f be the relation from x to y,

Then by the given table,

f(x) = { (0, 11), (1, 8), (5, 2), (4,5), (2, 9), (3, 6)}

∵ If for each input in a relation has exactly one output, the relation is called a function.

Here, for each value of x there is exactly one value of y,

Hence, f(x) is a relation from x to y,
