Fish aren’t going to win any races on land. But swimming in the pool is a different story. The sailfish, named for the funny fin along its back, can power through the water at up to 68 miles an hour — as fast as cars on a highway, and faster than a cheetah! Pushing through water is much harder work than running through air, so that’s pretty impressive speed – especially for a fish that weighs 200 pounds.

*Wee ones:* If a sailfish can turn blue, silver, purple, brown or gray, how many colors is that?

*Little kids:* If you swam alongside a 10-foot sailfish, how much longer than you would the fish be? (You can round your height to the nearest foot!) *Bonus:* If the sailfish swims 68 miles in an hour, and you drive your car 1 mile an hour faster, how fast is your car?

*Big kids:* No one knows the exact number, but scientists say cheetahs can run 59 miles per hour. If the sailfish can swim 68 miles an hour, how much faster is the fish? *Bonus:* The fastest human swimmer ever swam about 5 1/2 miles an hour. About how many times as fast is the sailfish? (Hint if needed: If the fish were just twice as fast, how fast would that be…?)

Answers:

*Wee ones:* 5 colors.

*Little kids:* Different for everyone…subtract your height in feet from 10. *Bonus:* 69 miles an hour.

*Big kids:* 9 miles an hour faster. *Bonus:* About 12 times as fast! Twice as fast would give us 11 miles an hour, and 68 is about 6 times as fast as that.
