Answer:

5.3 Hours

Step-by-step explanation:

I took the test online in K12 and when I reviewed it said that 5.3 is the correct answer.

The total time Maria's family spent driving to and from her grandparents' house is option D 5.3 hours.

  • The calculation is as follows;

To grandparents house:

\(= 140\div 56\)

= 2.5 hours

And,

Return trip :

\(=140\div 50\)

= 2.8 hours

Now

Total time is

=  2.8+2.5

= 5.3 hours
