Question

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

Answer 1

6

Explanation:

In this question it appears that for each burger Tom then has to eat 1 portion of fries. This combination would take 15 + 5 = 20 minutes.

Since 60/20 = 3, he would be able to eat 3 burgers and 3 portions of fries in 60 minutes. Making up a total of 3+3 = 6

Answer 2

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

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 =
`(1)/(20)`

∴ In 60 minutes he would be able to eat =
`(60)/(20)=3` sets of burgers and fries.

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