To practice for an Ironman competition, John swam 0.86 kilometer each day for 3 weeks. How many meters did he swim in those 3 weeks?

18,060

Step-by-step explanation:

0.86 kilometers is the same as 860 meters. If he swam 860 meters a day for twenty-one days, (860 times 21) he'd end up with 18,060 meters in total.

(That's about 722 1/2 lengths of a pool, but you didn't need to know that :P )

to rewrite a literal equation you may need to divide by a number, or by a variable.
