Question

The top speed of a wildebeest is 64 km/h and the top speed of a zebra is 64.4 km/h. How much faster is a zebra in feet per second? 1 km = 0.62137 miles. Round your answer to the nearest hundredths.

Answer 1

64 km x 0.62137 = 39.76768 miles per hour

64.4 x 0.62137 = 40.016228 miles per hour

40.016228 - 39.76768 = 0.248548 miles per hour faster

1 mile =5280 feet

5280 * 0.248548 = 1312.33 feet per hour

3600 seconds per hour

1312.33 / 3600 = 0.37 feet per second faster
