Question

help me help me help me help me help me please

Answer 1

E = Effies distance travelled

K = Kristen's distance travelled

 

The total distance travelled

will be 23.6 km split between

the two of them

 

1). E + K = 23.6

 

Effie travels 5.2 km less than Kristen

 

2). E = K - 5.2

 

Solve by substitution.  Replace E with

K-5.2 in equation 1 and solve for K.

 

(K-5.2) + K = 23.6

2K - 5.2 = 23.6

2K = 28.8

K = 14.4 km

 

E = K-5.2 = 9.2 km

 

Katie travels 14.4 km

Effie travels 9.2 km
