Rowing upstream for 5 mi against a strong current, your speed is 20% less than your normal rowing speed. On the return trip downstream, your speed is 20% greater than your normal rowing speed. Will you finish the whole trip in the same time as if you had rowed at normal speed throughout? How much longer than usual will your total time be?

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
