Charlie the snail is climbing up the Finley middle school flagpole. He climbs 10 inches in 10 minutes and then rests for 2 minutes. He continued at the same rate, climbing for 10 minutes and resting for 2 minutes. If the flagpole is 20 feet high, how many minutes will it take Charlie to reach the top of the flagpole?

Answer:

  • 4 hr and 46 min

Step-by-step explanation:

The flagpole is 20 feet = 20*12 in = 240 in high

The increments of 10 in take:

  • 10 + 2 = 12 min, the very last one takes 10 min only

The number of 10 in increments:

  • 240/10 = 24

Time required for Charlie:

  • 24*12 - 2 = 286 min = 4 hr and 46 min
