Ответ:
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
