Question

Andres completed a 5-km race in 13.5 minutes. His sisters time was 1 1/2 times longer than his time. How long, in minutes did it take his sister to run the race

## Answers ( )

Answer: 71.5minutes

Step-by-step explanation:

Andres

Distance 5km

Time= 13minutes

Andrea’s sister race covered = 11/2 of Andres’s distance

11/2*5=27.5km

5km=13minutes

27.5km=xminutes

5x=13*27.5

5x= 357.5

X=357.5/5

X=71.5minutes

It will take Andres’s sister 71.5minutes to complete her race
