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)
Well the order is pemdas
parenthasees, exponents, mutiplication or divistion whicher comes first left to right, then addtion and subtract whicherver comes first from left to right
so fractions are technically division, so just first simplify them, then do whaterver you want exg
1/2 times 4/8
first simpligy
1/2 times 1/2
multiply
1/2 times 1/2=1/4
A group owes someone 85 dollars. The group contains 15 people. So each each person in the group has to pay minimal amount of money, they decide to split the cost evenly. Each person in the group now owes about $5.67 to the person.
4004 + 50.50t = 300.75t
4004 = 300.75t - 50.50t
4004 = 250.25t
4004 / 250.25 = t
16 = t <=== they charge the same at 16 tons
300.75(16) = 4812 <== they cost the same
A is not part of the problem, and it's what makes the condition false. B is the opposite of the statement being proved. C is the condition, not the hypothesis. However, D is the statement we are trying to prove, or the hypothesis.
