Elena and Marcus jog after school each day. One day, Elena and Marcus jogged a total of 15 miles. Elena jogged 1 mile more than Marcus. Use a graph to find the number of miles each person jogged.
Accepted Solution
A:
This is the concept of algebra, let the number of miles jogged by Marcus be x, the number of miles jogged by Elena is (x+1) miles: Total number of miles jogged by the two individuals will be: x+(x+1)=15 2x+1=15 putting like terms together we get: 2x=15-1 2x=14 hence x=14/2 =7miles therefore we conclude that Marcus jogged 7 miles while Elena jogged 8 miles.
