Question

Rodrigo drove 91 miles east on the first day of his vacation. Then he drove 77 miles west on the second day. On the third day, he drove 59 miles east. How many miles east of the starting point is Rodrigo? (+91, -77, +59).

Answer 1

Sure, let's go step-by-step. We count +91 miles for east and -77 miles for west because they means Rodrigo drove towards the opposite direction.

1. Rodrigo started his journey and drove 91 miles East. At the end of the first day, his position from the starting point is 91 miles East.

2. On the second day, Rodrigo changed his direction and drove 77 miles West. So, we subtract these 77 miles from the distance he drove on the first day. After this day, his position from the starting point is 91 - 77 = 14 miles East.

3. On the third day, Rodrigo again drove towards East for 59 miles. So, we add these 59 miles to the total distance he was already East from his starting point. So, at the end of the third day, his position from starting point is 14 + 59 = 73 miles East.

So, Rodrigo is 73 miles east of the starting point at the end of his journey.
