40 minutes is 2/3 of an hour.
30 miles per hour x 2/3 hour = 20 miles.

60 miles per hour x 1/2 hour = 30 miles.
Total = 20 + 30 = 50 miles.
Answer:
The number of weeks required = 216 weeks
Step-by-step explanation:
Given that:
Margin of Error E = 200
Confidence interval = 95% = 0.95
Level of SIgnificance = 1 - C.I
= 1 - 0.95
= 0.05
Standard deviation = 1500
The Critical value for Z :

The number of weeks( i.e the sample size (n) ) required is :



n = 216.09
n ≅ 216 weeks
