Question

a man was trying to swim to a buoy placed at a distance of 200m out in the sea. it took him 1 min to swim 20m. then a wave pushed him back 10m and he rested for about 1min before swimming again. he continued in his way for the rest of their journey. how long would it take the man to swim to the buoy? sequence formula

Answer 1

37 minutes. he does 10m every 2 minutes until he does 180m for 36 minutes. then he does 20m for 1 minute bc the wave doesn't take him back. so it's 37 minutes
