Caleb's mother said they will drive 1 /4 hour to get there, and they will drive another 1 /4 hour back. Once they arrive, Caleb'
Nezavi [6.7K]

Answer: They are away for 2\dfrac{3}{4}\ hours from home.

Step-by-step explanation:

Since we have given that

Time to get there = \dfrac{1}{4}

Time to get back = \dfrac{1}{4}

Number of soccer games = 3

Time for each soccer games = \dfrac{3}{4}

So, total time for 3 games would be

3\times \dfrac{3}{4}=\dfrac{9}{4}

So, the time for which they will be away from home is given by

\dfrac{1}{4}+\dfrac{9}{4}+\dfrac{1}4}=\dfrac{1+9+1}{4}=\dfrac{11}{4}=2\dfrac{3}{4}\ hours

Hence, they are away for 2\dfrac{3}{4}\ hours from home.
