Give the answed of the question Doreen ran 4 miles farther than ludy. Together, they ran a distance of 20 miles.How far did each ran?

Answer 1

Runners: Lucy--> L =
Doreen -->D = L+4
Total miles ran is 20--> 20 = L + D
20 = L + L + 4
20-4 = 2L
16 = 2L
8 = L -> L = 8 mi.
D = L + 4 = 12 mi.
Double Check: 20 = L + D
20 = 8 + 12
