15. Tamika eats jellybeans at a rate of 12 jellybeans every 4 minutes. It takes her 30 minutes to eat the snack size pack of jellybeans. Her brother, James, eats jellybeans at a
rate of 28 jellybeans
every 7 minutes. How many fewer minutes does it take James
to eat a snack size pack of jelly beans compare to Tamika?

Answer :

In 1 minute, Tamika can eat jelly bean = :

12 : 4 = 3 ( jelly / mins )

Number of jelly in 1 pack =

30 × 3 = 90 ( jelly )

In 1 minute, James can eat jelly bean = :

28 : 7 = 4 ( jelly / mins )

The number of minutes James ate all the jelly bean = :

90 : 4 = 22, 5 ( mins )

=> James ate all the jelly bean : 22, 5 mins.

Step-by-step explanation:

tamika eats jelly beans at a rate of 3 jellybeans ber miniute since it would be 12/4. and it takes tamika 30 minutes which means that the snack pack had 90 jellybeans.

James eats jellybeans at a rate of 4 jellybeans per miniute so it took james 22.5 miniutes to eat a snack pack.

so you would subtract tamikas minutes(30 min) - james minutes(22.5) and get 7.5 minutes.

James took 7 minutes and 30 seconds less than Tamika to eat his jelly beans.
