You can use the formula 1/4 (where 4= the hours it takesJulie) + 1/6 (the time it takes Pat) = 1/t. You then add thedemoninaters, which = 10 (put this in the numerater). Then multiplythe denominater 4 * 6 = 24 (put this in the denominater). So t= thereciprical 24/10, which is 2.4 hours or 2:24 p.m. 1/4 + 1/6 = 1/t ---->1/t = 10/24 ------> t= 24/10---> t = 2.4 ---> 2:24 p.m. Hope this helps.Related Questions
