If a car travels 30 mi. north for one-half hour, 50. mi. east for one hour, and 30 mi. south for 30 min., what is the total distance the car traveled?
Answer:
110 mi
Explanation:
d1 = 30 mi, d2 = 50 mi, d3 = 30 mi
Distance is defined as the length of actual path traveled.
So, total distance, d = d1 + d2 + d3 = 30 + 50 + 30 = 110 mi
