9. Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was
speeding. The speed limit is 65 mi/hr and Sally had traveled 97 km in 102 minutes. How fast was
Sally’s average speed? Does she deserve a ticket?

10. An overzealous parkour jumper accidentally falls from a two story building. Don’t worry, his ninja-like
reflexes left him with only a minor ankle sprain (but don’t try this at home!) If the two story building was
20.0 ft tall, how many millimeters was this? (2.54 cm = 1 in).

1. Sally's average speed is 35.38 miles/hr. She deserves no ticket

2. The 20.0 ft tall building is 6096 mm tall.

Miscellaneous calculation

For the first problem, recall that: speed = distance/time.

The distance covered by Sally is 97 km within 102 minutes.

1 km = 0.62 miles

97 km =  0.62 x 97

            = 60.14 miles

60 minutes = 1 hr

102 minutes = 102/60

                    = 1.7 hours

The average speed of Sally can be calculated as:

               60.14/1.7 = 35.38 miles/hr

Since the speed limit is 65 mi/hr, this means Sally's speed is still within acceptable limits and does not deserve a ticket.

For the second problem:

1 ft = 12 inches

20 ft = 12 x 20

          = 240 inches

1 inch = 2.54 cm

240 inches = 2.54 x 240

                = 609.6 cm

1 cm = 10 mm

609.6 cm = 10 x 609.6

                 = 6096 mm

Thus, the 20.0 ft tall building is 6096 mm tall.
