Ответ:
Speed is distance/time so
[(d/20)+(d/24)]/2= 24d+20d/24•20•2=44d/20•24•2=22d/20•24=11d/240
Ответ:
-20 yards
Step-by-step explanation:
Given : Bobby’s football team received four five-yard penalties in the first quarter.
i.e. Number of five-yard penalties in the first quarter =4
It meant his team lost yardage in their progress toward the goal line.
Then, the change in their progression down the field as a result of these penalties :![4\times-5=-20\text{ yards}](/tpl/images/0368/1876/72710.png)
Hence, the change in their progression down the field as a result of these penalties = -20 yards
