**Q2: **

A river is one half mile wide with a current flowing at 2 miles per hour from east to west. A man can swim at 3 miles per hour in still water. He stands on the south bank, so how many degrees east of north should he head at this rate in order to travel directly north across the river? Give your answer correct to one decimal place. What would the answer to this problem be if the river flowed at 3 miles per hour and the man could swim only at the rate of 2 miles per hour?

- A ,
- B , it is not possible for him to head directly north in the second case.
- C ,
- D , it is not possible for him to head directly north in the second case.
- E , it is not possible for him to head directly north in the second case.

- D 4.64 miles, north of east
- E 4.64 miles, east of north

**Q4: **

A man started walking from home and walked 4 miles east, 2 miles southeast, 5 miles south, 4 miles southwest, and 2 miles east. How far did he walk in total? If he walked in a straight line back home, how far would he have to walk? Give your answer correct to three decimal places if necessary.

- A m, north of east
- B m, north of east
- C m, north of east
- D m, north of east

**Q7: **

An airplane was flying due north at 150 miles per hour . A wind was pushing the airplane due east at 40 miles per hour. After 1 hour, the plane started flying east of north.
