Problema Solution
A machine produces 264 bolts in 42 minutes. At the same rate, how many minutes would it take to produce 308 bolts?
Answer provided by our tutors
the rate of the machine is v = 264/42 bolts/min
let b = 308 bolts the number of bolts and t the time needed
since the rate is the same v = b/t thus we have
308/t = 264/42
by solving we find
t = 49 min
