There are four estimates made for the anticipated cycle time to produce a subcomponent. The estimates, in seconds, are $10,20,30,$ and $57\mathrm{.}0.$ If the first two estimates have equal weights, which total $78\mathrm{.}0\%,$ and the last two are weighted equally with the remaining $22\mathrm{.}00\%,$ what is the expected time?

The expected time is $$ seconds.
