## amber15 A wheel made 352 revolutions at 4 3/5 revolution per minute how many minutes did it rotate 9 months ago 9 months ago

the rpm is 23/5 now (rpm)(total minutes)=352 rev therefore total minutes = 352*5/23 total minutes = 76.5 or full revolutions 76

thank you

let the time be t so $\frac{ 352 }{ t } = 4\frac{ 3 }{ 5 } = \frac{ 23 }{ 5 }$ so on simplification t= 76.52
