Answer
After the third day, Rodrigo is 73 miles east of his strting point.
Step-by-step explanation
We are told that Rodrigo drove 91 miles east on the first day.
He then drove 77 miles west on the second day.
He then drove 59 miles east on the third day.
We are then told to calculate how many miles east from the starting point Rodrigo has travelled.
Rodrigo started from a point. Moved 91 miles east.
His position from his starting point = 91 miles east
He then drove 77 miles west on the second day. Since West is in the opposite direction to East.
His position from his starting point = 91 miles - 77 miles = 14 miles east
He then drove 59 miles east on the third day.
His position from his starting point = 91 miles - 77 miles
= 14 miles + 59 miles
= 73 miles east.
Hope this Helps!!!
