Question

1 meter/second is equal to
• 1000 inches
• 100 feet
• 3.28 feet/hour
• ~ 2 knots
• 10 kilometers/hour

Answer 1

Well it's a conversion factor so you have to end up with a length per time. that automatically rules out options 1,2.

1 meter does equal 3.28 feet but the time conversions are wrong so it's not that one. And using conversions, option 5 is wrong too. 1 knot = about 0.5 m/s so using that conversion factor, you just multiply both sides by 2 and get 2 knots = 1 m/s and that's your answer
