Question

Two sub-sandwich-shop workers serve approximately 100 sandwiches daily. Each worker can prepare four sandwiches in five minutes. Working together, how many sandwiches can they prepare in an hour?

Answer 1

as each worker can prepare 4 sandwiches/5miutes and there are 2 workers,

we can say in total 8 sandwiches/5minutes

Multiply denominator and numerator by 12.

96 sandwiches / 60minutes

= 96 sandwiches / hr

working together, they can make 96 sandwiches in an hour.
