A tennis ball travels at a speed of 120 miles per hour. Convert this rate to feet per second.
Answer (2)
120 h o u r mi l e 1 mi l e = 5280 f ee t 1 h o u r = 3600 seco n d s 120 h o u r mi l e = 120 ∗ 3600 5280 = 3600 120 ∗ 5280 = 3600 633600 = 176 seco n d f ee t 120 h o u r mi l e = 176 seco n d f ee t
A speed of 120 miles per hour is equivalent to 176 feet per second after converting units. This conversion uses the fact that there are 5280 feet in a mile and 3600 seconds in an hour. By multiplying the values and simplifying, we arrive at the final speed in feet per second.
