Question: Jack bought an ice cream cone before jogging to the beach. If the ice cream cone will melt in 10 minutes, the beach is 16 blocks away, and each block is 1/8th of a mile, how fast does Jack need to jog (in miles per hour) to get to the beach before the ice cream melts? Think carefully first, then make a decision:
First find the total distance to the beach: 16 blocks * 1 / 8 mile / block = 2 miles. Then find how long in hours Jack has to get to the beach: 10 minutes / 60 minutes / hour = 1 / 6 hour. Then divide the distance Jack needs to cover by the time in hours he has to find how fast he needs to jog: 2 miles / 1 / 6 hour = 12 miles / hour. So the answer is 12.
