<u>Answer:</u>
Speed of the boat in still water = 6.125 miles/hour
<u>Step-by-step explanation:</u>
We are given that a boat travels 33 miles downstream in 4 hours and the return trip takes the boat 7 hours.
We are to find the speed of the boat in the still water.
Assuming 
to be the speed of the boat in still water and 
to be the speed of the water.
The speeds of the boat add up when the boat and water travel in the same direction.
And the speed of the water is subtracted from the speed of the boat when the boat is moving upstream.
Adding the two equations to get:
+ 
___________________________
Solving this equation for and substituting the given values for 
:
Therefore, the speed of the boat in still water is 6.125 miles/hour.
Answer:
The answer is 71 miles
Step-by-step explanation:
According to the decimal rule, the Monday's 12.3 will be rounded off to 12,Tuesday 14.1 will be rounded off to 14, Wednesday 17.7 will be rounded off to 18 as .7 is greater than .5,Thursday 11.8 is rounded off to 12 and Friday to 15
To calculate how far she biked in all in five days we add all the distances she covered every day.So,
12 miles+14 miles+18 miles+12 miles+15 miles= 71 miles.
