Question

Since there are 5,280 feet in one mile and 3.3 feet in one meter how many meters per second are equivalent to 144 miles per hour

Answer 1

144 miles =  (144 * 5280) / 3.3   meters  =   230400 meters

230,400 meters  / hour  = 230,400 / 3600 meters / second (as  1 hour = 3600 s)

Answer  64 meters / second
