Gillian has completed 25% of a bicycle race. If the race is 40 miles long, how many miles has she traveled so far?

0.25 * 40 = _______ miles

To find out how many miles Gillian has traveled so far in the bicycle race, we need to calculate 25% of 40 miles.

To do this, we can use the following formula:

25% * 40 miles = (25/100) * 40 miles

Step 1: Convert the percentage to a decimal by dividing it by 100:
25/100 = 0.25

Step 2: Multiply the decimal by the total distance:
0.25 * 40 miles = 10 miles

Therefore, Gillian has traveled 10 miles so far in the bicycle race.
