How much time would it take you to swim across a lake that is 600 meters wide if you swim at 1.5 m/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?

Brandon is on one side of a river that is 5050 m wide and wants to reach a point 200200 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 22 m/s and run at 66 m/s.(We assume that the speed of the water is negligible compared with the speed at which Brandon swims.)(Use decimal notation. Give your answer to two decimal places.)

The time taken by a boat to go to a certain distance against the current is the same as to go the double distance along the current. The speed of the current is 3 km/h. How much time will the boat take to travel 57.6 km in still water?

The speed of a boat in still water is 6 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 22.5 km and comes back to the starting point. The total time taken by him is?Options10 hours4 hours 10 minutes6 hours 10 minutes8 hours

A motorbike races at 180 km/h. How many minutes does it take to travel 300 km?
