Question

Sue, Mohamed, and Kimi take turns driving a car from Kimi’s house to Vogel State Park, a total distance of 85 kilometers. If Mohamed drives 5 km less than 3 times as far as Sue, and Kimi drives twice as far as Mohamed, how far does Mohamed drive?

(Write solving steps as well)

Answer 1

25 km

let x be the distance travelled by Sue

then 3x-5 is the distance travelled by Mohamed

and 2(3x-5) is for kimi

so equation becomes

3x-5+x+2(3x-5)=85

10x-15=85

x=10

Mohmed travelled 3*10-5=25km
