Which is the fastest? [1 mile = 5280 ft; 1 meter is approximately 39 inches]

A) 2 meters per minute
B) 6 miles per hour
C) 10 feet per second
D) 15 yards per second

Answer :

Obviously 15 yards per second would be the answer 
I believe the answer is D) 15 yards per second

let's convert all of them into meter/hour


2 meters/minute = 120 meter/hour

6 miles/hour = 6x1609.34/hour = 9656.06 meter/hour

10 feet per second = 36000feet/hour  = 1097.28 meter/hour

15 yards per second = 54000 yards /hour = 49377.6 metr/hour >>>> Fastest
