Evelyn and Meredith decided to kayak 1 mile up and then back in the Humboldt channel.
Yakvenalex [24]

The rate of the water flowing in the channel was 2 miles per hour, the rate Evelyn and Meredith were paddling is mathematically given as

v+ = 2.29 1mile/hour

<h3>What is the rate Evelyn and Meredith were paddling?</h3>

Generally, the equation for the up and downstream motion is mathematically given as

vup=v-2

vdown=v+2

Therefore, Statement interpretation

2/3=40*1/60

3+2/3hr=11/3

Where, tup+tdown=11/3

tup+tdown=11/3

1/Vup+1/vdown=11/3

Considering the LCD equation

3(v-2)(V+2)

Hence

\frac{3(v-2)(v+2)}{v-2}+\frac{3(v-2)(v+2)}{v+2}=\frac{11(3)(v-2)(v+2)}{3}\\\\3(v+2)+3(v-2)=11(v+2)(v-2)

11v^2-6v-44=0

v=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Resolving using the equation we have

v+ = 2.29 1mile/hour

v- = -1.745 mile hour

A bus and a train leave the same station at the same time and travel in the same direction along parallel routes. The train runs
MrMuchimi

Answer:

Smallest rate for the train is 50 mph and largest is 60 mph.

For the bus it is 25 and 30 mph.

Step-by-step explanation:

If the speed of the train is 2x then speed of the bus is x mph, and the train travels twice as far as the bus in a given time.

Distance = speed * time

For the largest rate:

d =  2x * 0.5   for the train

x = d

0.5d  =  x       for the bus

d - 0.5d = 15

0.5d = 15

d = 30

So the rate for the train =  30 / 0.5 = 60 mph.

In a similar fashion we can show that the smallest rate for the train is

25/ 0.5 = 50 mph.
