Time = distance/speed
Since you want to find the time Holly spent riding, you need to divide her distance (24 miles) by her speed (6 miles/hour) to get the number of hours (4) that she rode. Her starting time added to the time spend riding will give her ending time. One must subtract the riding time from the ending time to find the starting time.
Selection A is appropriate.
Answer:
Equation: 
Solve for n: n = 112
Step-by-step explanation:
To first set up the equation, you need to look at the verbal description and translate into numbers and operations:
'three fourths a number' = 
'plus 8' = + 8
'is' =
'20 less' = - 20
'the number' = n
Put the expressions together:
'three fourths a number plus 8': 
'20 less than the number': n - 20
Set them equal to each other and solve: 
Add 20 to both sides: 
Subtract
from both sides: 
Multiply both sides by
: 
Solve for n: n = 112
