Step-by-step explanation:
90% completed (in percentage)
45 mi completed (in miles)
Thus, we can say:
45 is 90% of what number??
This "what number" is the total (what we are trying to find). Now, we let this "what number" part be equal to "x". Also, we know "IS" means "=" and "OF" means "*". Thus we can write:
45 is 90% of what number??
45 = 90% * x
90% converted to decimal is:
90/100 = 0.9
Thus, the equation becomes:
Solving for x:
The trip is 50 miles
