Answer:
A, Between 9 and 10 am
Step-by-step explanation:
The math is simple. between 9 and 10 theres 1 hour, and between 28 and 67 there are 39 P(t).
Between 10 and 15 there are 5 hours, and between 67 and 212 there are 145 P(t), which divided by 5 is 29.
You divide by 5 to get the same amount of hours to compare both
9-10 am= 39
10-15am/pm= 29
Therefore, the number of people increased faster between 9 and 10 am.
