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.

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

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
