Answer:

50 miles

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:


45=0.9x

Solving for x:


45=0.9x\\x=(45)/(0.9)\\x=50

The trip is 50 miles
