Bernardo hiked 12.8 km in june and 13.4 km in july. nicole hiked the same total distance as bernardo but hiked only 11.5 km in june. how far did nicole hike in july? a. 14.7 km b. 12.8 km c. 13.1 km d. 1.9 km

Total distance hiked by Bernardo in June = 12.8 km
Total distance hiked by Bernardo in July = 13.4 km
Then
The total distance hiked by Bernardo in June and July = (12.8 + 13.4) km
                                                                                       = 26.2 km
Now it is given in the question that Nicole hiked for the same total distance in June and July.
Also it is given that
The distance hiked by Nicole in June = 11.5 km
Then
the distance hiked by Nicole in July = (26.2 - 11.5) km
                                                         = 14.7 km
So the distance hiked by Nicole in July is 14.7 km. The correct option among all the options given in the question is option "A".
