Answer:
40 tablets
Step-by-step explanation:
What we want to do is find how many mg of antihistamine you can take in a week.
If you can take 19mg in 6 hours, that means you can take mg per day (because , so you can take 19mg every 6 hours 4 times in a day.)
There are 7 days in a week, so you can take mg per week.
Now, we know how many mg of antihistamine you can take per week. If we take antihistamine in increments of 13.2mg, then the total amount of tablets we can take per week is going to be , which is approximately equal to 40.
So you can take 40 tablets in a week if you are 100 pounds.
Hope this helped!
Step-by-step explanation:
Since Bridget rows 1 hour 4 kilometers upstream and 30 minutes (half of one hour) kilometers, downstream, then we have to find the average speed of both times. First, let's find how long Bridget would have to row upstream every kilometer.
Step 1:
60 minutes ÷ 4 kilometers = 15 minutes per kilometer (upstream)
30 minutes ÷ 4 kilometers = 7.5 minutes per kilometer (downstream)
Step 2:
Now, we find the average of 15 and 7.5. To do that, we add the values together and divide them by the number of values there are (2).
15 + 7.5 = 22.5
22.5 ÷ 2 = 11.25
Answer: Bridget takes 11.25 minutes to row 1 kilometer in still water.
