The answer will be 21u^6v^8
hold on i will send in the comments i’m working on it rn
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

11v^2-6v-44=0

Resolving using the equation we have
v+ = 2.29 1mile/hour
v- = -1.745 mile hour

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.
