Answer:
Maya is hiking down at a speed of 100 feet per hour.
Step-by-step explanation:
Given that Maya is hiking down a mountain, and after one hours she is at 500 feet elevation while after three hours she is at 300 feet elevation, to determine the speed at which Maya is hiking down the following calculation must be performed:
3-1 = 2
500-300 = 200
200/2 = 100
Thus, Maya is hiking down at a speed of 100 feet per hour.

There seems to be a typo. You wrote 1313, but I'm assuming you meant to say the fraction 1/3. If this assumption is correct, then continue with the rest of the solution. If the assumption is not correct, then ignore what I wrote below and please provide clarification of what the "1313" should represent. Thank you.
----------------
B = your brother's age
S = your sister's age
Y = your age
All of these ages are current present day ages.
---------------
"your brother is 1/3 your age" so B = (1/3)Y or B = Y/3.
"Your sister is 6 years older than your brother" so S = B+6
"Your sister is 10 years old" so S = 10.
---------------
S = B+6
B+6 = S
B+6 = 10 ... plug in S = 10
B+6-6 = 10-6 ... subtract 6 from both sides
B = 4
Your brother is 4 years old.
---------------
B = Y/3
Y/3 = B
Y/3 = 4 .... plug in B = 4
3(Y/3) = 3*4 ... multiply both sides by 3
Y = 12
note: This answer hinges on assumption that the "1313" should be "1/3".
Work out the annual rate of simple interest.
Answer:
2.4%
Step-by-step explanation:
Simple interest (I) is calculated as
I =
where P is the principal, R the rate of interest and T time in years
Here I = 96, P = 800 and T = 5, thus
96 = = = 40R ( divide both sides by 40 )
R = = 2.4%
