Use the information given to correctly complete the sentence.
a scientist observes that a zebra ran 54 yards in 135 seconds.

the zebra ran at a rate of feet per minute.

72feet/min

Step-by-step explanation:

The following were obtained from the question:

Distance = 54 yards

But: 1yard = 3feets

Therefore, 54 yards = 54 x 3 = 162feets

Time = 135secs

Recall: 60secs = 1mins

Therefore, 135secs = 135/60 = 2.25mins

The rate of the Zebra = Distance /time

The rate of the Zebra = 162/2.25 = 72feet/min

Explanation: 54 yards is about 162 feet, and since we are converting measurements we need this ( duh ) and 135 seconds is approximately 2.25 minutes, so what we need to do is is divide the numbers like any conversion problem: 162 divided by 2.25  is 72.

Hope this answer helps!
