Question

A sandwich shop prepares 3 sandwiches in 126 seconds and 8 sandwiches in 336 seconds. At this rate, how many seconds will it take to prepare 5 sandwiches?

Answer 1

Answer: 210 seconds.

Time ÷ sandwiches

126 ÷ 3 = 42

336 ÷ 8 = 42

So it takes 42 seconds to make 1 sandwich.

42 seconds × 5 sandwiches = 210 seconds.
