If i drove 252 miles and that was 35% of the distance , how many miles is my trip total?

720 miles
Why?
Let x represent the number of miles your trip is in total.
Therefore, this is your expression;
0.35x = 252
35 percent of your total miles is how much you’ve driven so far, 252 miles.
Now, switch the equation around so that x is by itself.
x = 252/0.35
x = 720
Therefore, the total number of miles your trip is is 720 miles.
Check:
0.35(720) = 252
