Exercise 16 Page 31

When multiplying conversion factors, make sure the only remaining units are the desired units.

26cm/s=15.6m/min

Practice makes perfect
Let's start by writing the given statement. 26 cm/s= m/min In this exercise, we need to change centimeters per second into meters per minute. Let's start by organizing the relationships between the units in a table.
Starting Unit Converted Unit Unit Ratio
100 centimeters 1 meter 100cm/1m
60 seconds 1 minute 60s/1min
To perform this conversion, we need to multiply 26 centimeters per second by each unit ratio or its reciprocal. Remember, we want to arrange these ratios such that each unit we do not want gets canceled out, and only the units that we want will remain.
26cm/1s * 1m/100cm * 60s/1min
26cm * 1m * 60s/1s* 100cm* 1min
26 cm * 1m * 60 s/1 s* 100 cm* 1min
26 * 1m * 60/1* 100 * 1min
1560m/100min
15.6m/min
We can now complete the given statement. 26 cm/s=15.6 m/min
