D. is the answer
y - y1 = m(x - x1)
the slope is 2/3, so choose which point to be (x1, y1)
Automatically we know that he is wrong because even if we round it to make it a friendly number (lets say 1) it will still not equal 3 1/2
he has them for 3 1/2 days
even 1+1+1= 3 it still isnt enough and you arent even supposed to round
That is why he is wrong :) hope this helped
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".
