Freddie the frog was standing on one side of a pond. He had to jump across 17 lily pads to get to the opposite side. For every 4 jumps ahead, he took 1 jump back. If it took 3 seconds to make each jump, how many seconds did he take to get to the other side?
Number the 17 pads between the banks 1–17. One jump crosses one adjacent gap; the far bank is one jump beyond pad 17. Freddie stops as soon as he reaches it.
