Question 323836
A machine produces 192 bolts in 36 minutes.
 At the same rate, how many minutes would it take to produce 256 bolts?
:
Use a ratio equation here, let t = time to produce 256 bolts
:
{{{192/256}}} = {{{36/t}}}
Cross multiply
192t = 256*36
192t = 9216
t = {{{9216/192}}}
t = 48 minute to produce 256 bolts
