A) 3:11
b) 11:8
this should be correct
Answer:

Step-by-step explanation:
Distance can be found using this formula:

Where (x₁, y₁) and (x₂, y₂) are the points.
We are given the points O (-3, -2) and P(-3,4). Therefore,

Substitute the values into the formula.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Solve inside the parentheses first.
- (-3--3)= -3+3=0
- (4--2)= 4+2=6

Solve the exponents.

Add.

Take the square root.

The distance is 6.
Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5
Answer:
t=2
