Question

A cruise ship is traveling at a speed of

20 knots. A knot is approximately equal to 1.151 miles per hour. What is the
approximate speed the ship is traveling in yards per second? Round to the
nearest tenth.

Answer 1

1 mile = 1760 yards

20 * 1.151 = 23.02

23.02 * 1760 = 40,515.2

40,515.2 / 60 = 675.243~

675.243~ / 60 = 11.2542~

They are traveling 11.25 yards per second

I took the number of knots multiplied by the approximate miles per hour. Then multiplied that by the number of yards in a mile, and then divided that by the number of minutes in an hour, and divided that by the number of seconds in a minute. That is how I got the answer!

when rounded to tens, the answer is 11
