SOLUTION MAP
RELATIONSHIPS USED
1 m = 39.37 in. (Table 2.3)
1 ft = 12 in. (by definition)
SOLUTION
108 \cancel{ft}\times \frac{12 \cancel{in.}}{1 \cancel{ft}} \times \frac{1 m}{39.37 \cancel{in.}}= 32.918 m
= 32.9 m
The answer has the right units (meters), and it makes sense; because a meter is longer than a foot, the number of meters should be less than the number of feet.
Table 2.3
| Some Common Units and Their Equivalents |
| Length |
| 1 kilometer (km) = 0.6214 mile (mi) |
| 1 meter (m) = 39.37 inches (in.)
