Answer:
76 cm
Step-by-step explanation:
P=2L+2w
324=2(86)+2w
324=172+2w
324-172=2w
2w=152
w=152/2
w=76 cm
If he's average speed per minute is 1,448 meters per minute, and there are 60 minutes in a single hour. You would multiply 1,448 by 60 to get the answer of 86,880 meters per hour.
546 divide by 6 = 91 so 91 times 6 = 546
3 minutes = 2850
5 minutes = 4750
In 8 minutes he descended = 7600
1 min = 7600/8 = 950ft per min
Hope i become the brainliest answer.
