We have been given that Olga’s family traveled 942 kilometers on the first day.
And 894.5 kilometers on the second day.
We need to find how many more meters did Olga’s family travel on the first day.
Therefore, we must subtract the distance traveled in first day to the distance traveled in the second day of the trip.
Hence, the difference is given by
[tex]942-894.5\\
\\
45.5[/tex]
Thus, Olga’s family travel 45.5 km more on the first day.
