A scientist observed that a zebra ran 54 yards in 135 seconds. The zebra ran at a rate of blank feet per min
To find the rate at which the zebra ran in feet per minute, we first need to convert yards to feet and seconds to minutes.
Knowing that 1 yard is equal to 3 feet, and that 1 minute is equal to 60 seconds, we can calculate:
54 yards * 3 feet/yard = 162 feet
135 seconds / 60 seconds/min = 2.25 minutes
Now we can calculate the rate:
162 feet / 2.25 minutes = 72 feet/minute
Therefore, the zebra ran at a rate of 72 feet per minute.
