5/9 of the capacity of a tank has been used and there are still 108L left. What is the capacity of the deposit?

Step-by-step explanation:

The distance is  

Step-by-step explanation:

From the question we are told that

   The speed at which Gabby rode his bike is  

   The average speed of the car is  

   The distance from Gabby's house to the parents house is  

   The time taken for Gabby to get to his parents house is  t =  9 hours

Generally the distance from Gabby's house to his parent house is mathematically reparented as

Here is the distance from Gabby's house to his sisters house which is mathematically represented as

=> Here is the time taken to move from Gabby's house to his sisters house

while   is the distance from his sisters  house to his parents house which is mathematically represented as

So

=>  

Generally the total time taken to arrive his parents house from his house is mathematically represented as

=>    

Solving equation 1 and 2  simultaneously we have that

multiply equation 2 by 18  and equation 1 by 1

Substracting equation 3 from 4

=>    

=>    

substituting into equation 2

=>    

So the distance  from Gabby's house to his sisters house is mathematically represented as

=>
