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

we know that

64.4 km/h-64 km/h-------> 0.4 km/h
the zebra is 0.4 km/h much faster

1 km---------> 3280.84 feet
0.4 km---------> X
X=0.4*3280.84-----------> 1312.336 ft

the zebra is 1312.336 ft/h much faster
1 hour----------> 3600 sec
then
1312.336 ft/ 3600 sec----------> 0.36 ft/sec

the answer is 0.36 ft/sec
