Leave for Loafing Around — What Did Iluka Miss?
Lesson 9 of 12
About this lesson
Iluka is in the queue at Sliced Bread Sangers. He calculates that Loafing Around's 10-minute making time plus less-than-5-minute walk beats Sliced Bread Sangers' 15 minutes — so he decides to leave. Which sentence shows his mistake? He's done the maths correctly on the numbers he used, but he's left out a crucial variable: the queue at the other bakery.

Iluka: "Sliced Bread Sangers always take 15 minutes to make my favourite sandwich. But the Loafing Around bakery down the road always take 10 minutes. It takes less than five minutes to walk there – so I should head to Loafing Around and then I'll get my sandwich sooner."
