Liam is a tyre fitter. it takes him 56 minutes to fit 4 tyres to a van. a) how long would it take him to fit 12 tyres to 3 vans? b) if he works for 42 minutes, how many tyres can he fit?

I would first solve how long it takes for 1 tyres to make life easier. Just solve 56 divided by 4, which means that Liam takes 14 minutes to put one tyres into the van. For part a, I don't quite understand the 3 vans part, but you know he 's putting 12 tyres into a van, so multiply 12 by 14 to get 156. Part B gives you time instead of tyres. Solve it practically the same... 42 divided 14  is 3, so he fits 3 tyres in 42 minutes,

Part a)  or  

Part b)

Step-by-step explanation:

Part a) Using a proportion

Part b) Using a proportion
