A person desires to reach a point that is 2.80 km from her present location and in a direction that is 35.0° north of east. However, she must travel along streets that are oriented either north-south or east-west. What is the minimum distance she could travel to reach her destination?

Answer 1

2.80km[35o]
X = 2.80*cos35 = 2.29 km
Y = 2.80*sin35 = 1.61 km

dmin = 2.29 + 1.61 = 3.9 km
