If 1 mile is equal to 1.6 km, then our dimensional analysis would be set up like this to solve for m per hour:
. The miles label cancels out leaving us with kkm per hour. Doing that multiplication gives us 12.8 km in one hour. If she can go 12.8 m in one hour, then we multiply that by 2 to find out how far she can go in 2 hours. 12.8*2 = 25.6 km in 2 hours.

Answer:
Option number B
Step-by-step explanation:
As per the statement:
Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
Given the equation as:
7h - 5 ( 3h -8 ) = -72
Using distributive property,
a ⋅ ( b + c ) = a ⋅ b + a ⋅ c
7h - 15h + 40 = - 72
Combine like terms;
-8h + 40 = -72
Subtract 40 from both sides we have;
-8h 8= -112
Divide both sides by -8 we have;
h = 14 hours
Therefore, the statement is true about Pieter’s solution is, It must be a positive number since it represents a number of hours.
