MHB Rate problem....Am I in the right direction

[Francisco2022]

a. Emily works in the canteen and sells on average 16 Banana milkshakes,
13 baked macaronis, 5 Cauliflower Fried Rices, 25 Blueberry Muffins in one break.
Each break at the cafeteria is 30-min-long.

How long is it likely to take Emily to sell
50 Banana Milk Shakes,
34 Baked Macaronis,
25 Cauliflower Rices and
43 Blueberry Muffins?

So in 30 min, she sells
16 Banana M
13 Baked Mac
5 Clf Rice
25 Blueberry Muff...

Dividing each one by 30 we get how much she sells in 1 min:
16/30 = 0.5 Banana M per min
13/30 = 0.4 B Mac per min
5/30 = 0.17 Clf Rice per min
25/30 = 0.8 Blueb Muff per min

Sounds good... so if Emily sells 0.5 Banana Milk Shakes per minute, how long does it take her to sell 50?

not quite, the whole question is
How long is it likely to take Emily to sell
50 Banana Milk Shakes, 34 Baked Macaronis, 25 Cauliflower Rices and 43 Blueberry Muffins?

So you did not understand what Klas Van Arsen said! He was not handing you the answer he was showing you how to do the problem. If she makes 1/2 banana milk shake per minute, how long does it take to make 50? If she sells 0.4 baked macaroni per minute, how long does it take to make 34? Do that for each if the others.
