Answer:
4 minutes.
Step-by-step explanation:
There are three trains that Rachel has to take to go to her job. The total time is taken by her, on average, 1 hour and 20 minutes i.e. (60 + 20) = 80 minutes.
In his journey, she walks for 15 minutes and a train journey for about 53 minutes.
Then the total waiting time for the trains is (80 - 53 - 15) = 12 minutes.
Therefore, the average waiting time, in minutes, at each of the three train stations will be
minutes. (Answer)

Answer:
Step-by-step explanation:
A grocery store has a 13%-off sale on all bread.
Let b represent the original price of a loaf of bread.
This means that the amount by which the price of bread was reduced would be
13/100 × b = 0.13 × b = 0.13b
The new price for the loaf of bread would be
b - 0.13b
you decide to purchase 6 loaves of bread. The expression would be
6(b - 0.13b)
Expanding the expression, it becomes
6b - 0.78b
1 hour = 60 minutes
60 minutes / 10 minutes = 6
So 6 times in one hour 3 buses depart.
6 x 3 = 18 total buses in an hour.
