A) total distance covered = 60miles
B) total time taken = 4hrs 30 mins
Step-by-step explanation:
Detailed explanation and calculation is shown in the image below
Because the radius is properly the same or the volume is the same
I believe the answer is c
So, she has 3hrs to grade all papers, for 35 students.. alrite.
the first 5, she does them in 30minutes.. what's the speed rate? well, 5/30 or 1/6
now, she has still 2 hours and a half, or 150 minutes, to do the remaining 30 papers... she has to work at a rate of 30/150 then... which is 1/5 simplified.
now if we take 1/6 as the 100%, what is 1/5 in percentage then?

so 1/5 is 120% in relation to 1/6... meaning the rate of 1/5 she needs to move through, namely 1 paper every 5 minutes, is 20% faster than 1/6.
Answer:

Step-by-step explanation:
The experimental probability is
P (heads) = number of heads/ total tosses
= 8/20
= 2/5
