if three bakers can prepare 15 cakes in 6o minutes how long will it take six bakers working at the same rate to prepare 20 cakes
:
Find how many "baker-minutes" per cake
%283%2A60%29%2F15 = 12 baker/min per cake
:
"long will it take six bakers working at the same rate to prepare 20 cakes "
let m = no. minutes to accomplish this
6m = 20(12)
6m = 240
m = 240/6
m = 40 min for 6 to do 20
