Problem:                   If Kevin drives one mile in 80 seconds, what is his speed in km/sec?

Step 1: One mile is covered in 80 seconds; Speed = 80 mile/sec

Step 2: 1 mile = 1.6 km    Convert miles to kilometers

Speed = 1/80 mile/sec =1 x (1.6)/80 km/sec

                                                            Step 3: Speed in km/sec= 0.02

                                                             Step 4:                  The answer is:  0.02 km/sec
