Answer:
5 minutes
Step-by-step explanation:
If the mean arrival rate is 0.2 students per minute, the expected time interval between student arrivals, in minutes, is determined by the inverse of the arrival rate:
The interval between student arrivals is, on average, 5 minutes.
Since they are similar you need to start by making ratios for each pentagon.
1.8/2.4 is the first and x/3.6 is the second. Now set them equal to each other and cross multiply.
1.8 X
___ = ____
2.4 3.6
2.4x= 6.48 Now divide both sides by 2.4
2.4x= 6.48
___ ____
2.4 2.4
X= 2.7
