_{D}= 1/8Rate

_{E}= 1/6Distance covered by Daneka = 0.5 + T/8

Distance covered by Eric = T/6

Set distances equal to each other: 0.5 + T/8 = T/6

combine like terms: 0.5 = T/6 - T/8 (convert to common denominator)

0.5 = 4T/24 - 3T/24 = T/24

cross multiply to get T (time in minutes) by itself: T = 24*0.5 = 12 min
