Answer:
it will last 18 days
Step-by-step explanation:
divide 42 by 2 1/3
2 1/3 = 7/3
42 / 7/3 =
42 * 3/7 =
126/7 = 18
if this isn't enough then here
The number of days it will take the dog to consume the 42 cup of food will be 18 days.
Total cups of dog food = 42 cups
Amount of cups consumed per day =
To obtain the number of days it will take to consume the entire food :
Divide the total amount of food by the amount consumed per day
Hence,
(42 ÷ (7/3))
Take the reciprocal of 7/3 and change the operation sign to multiplication
42 × 3/7 = (42 × 3) / 7 = 126 / 7 = 18 days
Therefore, it will take the dog 18 days to finish up the 42 cups of food.

Answer:
56 min
Step-by-step explanation:
An hour and 15 minutes. Since Joe is driving 20 miles per 1/2 hour that means he is driving 40 miles every hour. We still have 10 miles left and since 20 divided by 2 is ten you would simply cut the time it takes him to drive 20 miles in half making 15 minutes. Then you add the time it takes to drive 40 miles and 10 miles and that's how you get an hour and 15 minutes. Hope this made sense!
