1. an emu can run 31 miles per hour. what is the emu's speed in feet per second?
Answered by Ms. Sue
1 hour = 3,600 seconds
1 mile = 5,280 feet

31 * 5,280 = 163,680 feet

163,680 / 3,600 = 45.47 feet per second

Yes. You're right. I just rounded it to the nearest hundredth of a second.

Sorry -- I rounded to the nearest hundredth of a foot.

Were you told to round to a thousandth of a foot?
