Zane knows t the absolute fastest his fishing boat can go is

Zane knows t the absolute fastest his fishing boat can go is 25 km/h. He wants to use his boat to cross a river t runs east-west and is 6.2 km wide to get to the train station t is straight across the river from his landing. He can\'t leave before 9 am and must get there by 9:15 am in order to catch the 9:15 train. Some days the river current is as fast as 5 km/h and some days it is as slow as 3 km/h. Determine whether Zane should attempt this trip to try to catch the train. Include a labeled diagram and be sure to show or explain how you arrived at your answer.

Solution

maximum time the boat can take = 6.2/28 *60mins = 13.29mins (as 25+3km/hr is the minimum speed it can gain)

So, Zane can attempt to go to the station(if we assume that the current is always along the direction of the boat)
