52 cm 1 s 100

$Additional Example 3 Continued It may help to eliminate the fraction 52 cm =$

Additional Example 3 Continued It may help to eliminate the fraction 52 cm = 1 s 100 • 52 cm 1 s 100 = 5200 cm 1 s 1 first. 100

Additional Example 3 Continued Now convert centimeters to meters. 5200 cm 1 s 1 m = 5200 cm • 100 cm 1 s 5200 m = 52 m = 1 s 100 s The object is traveling 52 m/s.

Check It Out: Example 3 65 cm 1 s 100

$Check It Out: Example 3 Continued It may help to eliminate the fraction 65$

Check It Out: Example 3 Continued It may help to eliminate the fraction 65 cm = 1 s 100 • 65 cm 1 s 100 = 6500 cm 1 s 1 first. 100

Check It Out: Example 3 Continued Now convert centimeters to meters. 6500 cm 1 s 1 m = 6500 cm • 100 cm 1 s 6500 m = 65 m = 1 s 100 s The object is traveling 65 m/s.
