Answer:
Lacey will bike 62.5 miles over 25 school days.
Explanation:
Lacey bikes 2.5 kilometers each school day. In total, how far will Lacey bike over 25 school days?
If Lacey bikes 2.5 kilometers in one day, then to find out how many miles she will bike in twenty-five days, we need to multiply 2.5 by 25.
2.5 x 25 = (25 x 2) + (.5*25) = 50 + 12.5 = 62.5 miles
Therefore, Lacey will bike 62.5 miles over 25 school days.
