In this question it is already given that a person travels 8 miles in 0.5 hours. This is enough information to get to the required answer. Let us first write down all the information's that are already given in the question.
In 0.5 hours the person covers a distance = 8 miles
Then
In 1 hour the person covers a distance of = 8/0.5 miles
= 16 miles
So the speed of the person in miles per hour = 16/1 miles/hour
= 16 miles per hour
Answer:
D = n/5 - m^2
Step-by-step explanation:
work:
n = 5(m^2 + D)
distribute the 5
n = 5m^2 + 5D
move the 5 to the other side by subtracting from both sides
n - 5m^2 = 5D
Divide both sides by 5 to isolate D
n/5 -m^2 = D
use reflexive property to get the answer on the left side
D = n/5 - m^2
