Answer: The required probability is 0.6.
Step-by-step explanation:
Since we have given that
It is uniformly distributed between 40 minutes and 90 minutes,
Probability that her trip will take longer than 60 minutes would be

here, a = 40, b = 90, α = 60

Hence, the required probability is 0.6.
Using the formulas
A=πr2
C=2πr
Solving forC
C=2πA
Your answer: 21.27
76/100
19/25
To simplify divide by 4
Answer:
0.1
I divided both of them and got 0.1
