Answer:
- <u>They can catch up with the bus at 10:40 am.</u>
Explanation:
1. Set the time when Liana and her mother can leave (8:40 am) as t₀ = 0; thus the time of driving for them will be t.
2. The average speed at whic Liana's mother drive: 60 miles/hour
3. Thus, the distance they will have driven will be:
- distance = average speed × time = 60t
4. The time the bus left was 8:00 am, which is 40 minutes before Liana and her mom can leave.
Thus, the time wil have driven when Liana and her mom have driven t hours minutes will be: t + 40 min / 60 min/ hour = t + 2/3
5. The average speed of teh bus is 45 miles / hour
6. The distance the bus will have driven will be:
- distance = average speed × time = 45(t + 2/3)
7. When Liana and her mother catch up with the bus, the distances driven by both of them are equal:
Thus, Liana and her mom can catch up with the bus after 2 hours, since 8:40 am; this is, 10:40 am.

Answer: P < 300 = 0.102
Step-by-step explanation:
Suppose the round-trip airfare between Boston and Orlando follows the normal probability distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = the round-trip airfare between Boston and Orlando.
µ = mean
σ = standard deviation
From the information given,
µ = $387.20
σ = $68.50
The probability that a randomly selected airfare between Boston and San Francisco will be less than $300 is expressed as
P < 300
For x = 300,
z = (300 - 387.20)/68.5 = - 1.27
Looking at the normal distribution table, the probability corresponding to the z score is 0.102
Answer: x*3= 3x
