Liam is a tire fitter it takes hime 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 Tyers can he fit?

a) 168 minutes or 2 hours and 48 minutes

b) He can fit 3 in 42 minutes

Step-by-step explanation:

so first find how long it takes for one.

56 minutes divided by 4 is 14.

so, it takes 14 minutes for each one.

so, to fit 12 then you will need to multiply 12×14 to get 168.

168 minutes = 2 hours and 48 minutes.

and for the last part on part B, 14×3=42. He can fit 3 in 42 minutes.

Hope this helps some!

Have a great day!

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
