A boat is crossing a wide river flowing at 8 km/hr. from west to east. The landing port is exactly the opposite of the starting point on the south bank of the river. If the boat moves at 10 km/hr. to cross the river and crosses it in 1/2 hr., what is the width of the river?

A river 100 m wide flows due south at 1 m/s. A boat that travels 1 m/s relative to the water is pointed due east as it crosses from the west bank. The boat reaches the east bank Group of answer choices100 m farther south141 m farther south100 m east of its starting point100 m farther north

A motorboat can move with a maximum speed of 10 m/s relative to the water. A current isflowing at 5 m/s [E]. What course (direction) should the boat take in order to cross a 400 mwide river and land at a point directly opposite to the starting point? How long will the triptake? (Answer: [N30oW]. 46 s)

A swimmer's speed with respect to still water is 77 m/s. She wants to cross a river 111111 m wide and with a current at 11 m/s speed. If an observer at the shore sees that the path is straight across the river, how long does it take for the swimmer to get to the other side of the river? What upstream angle does she need to swim directly to the other side?

A boat sailing through a river moved eastward for 5 km, then cross the river by moving 3 km southward. On reaching the other side it moved westward through 1 km and reached the dock. Find the distance covered by the boat in km.

Two boats leave the same marina. One heads north, and the other heads east. After some time, the northbound boat has traveled 16 miles. If the two boats are 20 miles apart, how far has the eastbound boat traveled?
