Math HW, please help:
At its maximum speed, a motorboat can travel 10 miles downstream on a river in 20 minutes. It takes 30 minutes for the boat to travel back upstream the same 10 miles, also at maximum speed.
Write a system of two equations that could be used to find the maximum speed of the motorboat in still water. Let b represent the maximum speed of the motorboat in miles per hour and let r represent the speed of the river's current in miles per hour. Convert the times into hours. Solve the system of equations for b and r to determine the boat's maximum speed in still water and the speed of the river's current.

(NOT MATH ITS SCIENCE HELP PLEASE)If a builder wanted to construct a shopping mall on a barrier island, which of the following questions would be the most significant concern for him to consider?

A.
Where would be the best place to build the mall so that it is protected from the impact of storms which causes the winds and waves to constantly redistribute the sand?

B.
Before construction begins, should large amounts of sand be removed from the
island first in order to prevent erosion of the beach?

C.
Since the islands are constantly changing, what location would offer the best access to sand resources to aid in maintaining the island?

D.
If an earthquake were to occur, would the islands sink below sea level, causing a tsunami to crash on the mainland

A time line is a useful way to represent important dates and events throughout history. It's common to divide a historical time line into events that occurred either BC (to the left of zero) or AD (to the right of zero). The year you're living in right now takes place in AD. BC AD 0 When performing mathematical operations involving dates, we can think of a historical time line as a number line. On the number line, the years increase from left to right. If zero represents the origin, the years to the right of zero are considered positive numbers and the years to the left of zero are considered negative numbers. Using this analogy, here are some events that might appear on a historical number line:
Event Historical Time Line Number Line

(The first ancient games take place in Olympia, Greece. 776 BC -776)

(Construction begins on the Great Wall of China. 221 )

(BC -221 World War I begins in central Europe. AD 1914 1,914 (or 1914)

Use these ideas about time lines and number lines to answer the questions that follow.
Part A The year in which the US Civil War ended was 25 percent later than the year Christopher Columbus set sail from Spain. If c represents the year Columbus set sail, we can write the year the Civil War ended as C +0.25c.
