If it takes tom 15 minutes to eat a burger and then 5 minutes to eat a portion of fries, how many burgers and portions of fries would he be able to eat in one hour?
but my options are, 3,6,2,and 5

Tom eats 3 burgers and 3 portions of fries in 1 hour.

Step-by-step explanation:

Tom eats a burger in 15 minutes and a portion of fries in 5 minutes.

Total time he spent = 15 + 5  = 20 minutes in eating both

We have to calculate the number of burgers and fries he is able to eat in one hour.

∵ In 20 minutes Tom eats burger and fries = 1

∴ In 1 minutes he would be able to eat =

∴ In 60 minutes he would be able to eat = sets of burgers and fries.

Therefore, Tom eats 3 burgers and 3 portions of fries in 1 hour.

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
