Andre is working from home to a festival that is 1 5/8 km away. He takes a quick rest after walking 1/3 km what fraction of the

Anton [14]

Answer:

The fraction of trip completed by Andre is $\frac{31}{24}$ km

Step-by-step explanation:

Given as :

The Total distance between the home to a festival = 1 $\frac{5}{8}$ km

I.e The total distance between the home to a festival = $\frac{13}{8}$ km

The distance cover by Andre before taking rest = $\frac{1}{3}$ km

Let The fraction of trip completed by Andre = x km

So, <u>According to question</u>

The fraction of trip completed by Andre = The Total distance between the home to a festival - The distance cover by Andre before taking rest

or, x = $\frac{13}{8}$ km - $\frac{1}{3}$ km

or, x = $\frac{39 - 8}{24}$ km

∴ x = $\frac{31}{24}$ km

Or, The fraction of trip completed by Andre = x = $\frac{31}{24}$ km

Hence , The fraction of trip completed by Andre is $\frac{31}{24}$ km Answer
