Damon can flip 5 pancakes in 20 seconds,

working at a constant rate. Hailey can flip
2 pancakes in 10 seconds, working at her
own constant rate. What is the total number
of pancakes the two of them can flip in 2
minutes?

Answer:

54

Explanation:

2 minutes=120 seconds

Damon=120 divide 20=6

6x5=30

Hailey=120 divide 10=12

12x2=24

24+30=54

Hope this helps! Thanks.

Answer:

24 + 30 = 54 pancakes flipped in 2 minutes :)

Explanation:

damon = 5 pancakes in 20 seconds

we do 20 x 3 and 5 x 3 to find how many pancakes he can flip in a minute

15 pancakes and a minute, we then multiply them by 2 to get the amount for 2 minutes

30 pancakes flipped in 2 minutes

Hailey = 2 pancakes in 10 seconds. to make it an equal amount of pancakes per second with damon, i will multiply them by 2 to have 4 pancakes in 20 seconds

we will then do 4 x 3 and 20 x 3 to find out how many pancakes per minute

then we multiply by 2 for 2 minutes
