Use the rules for multiplication and division of measurements to find the value of each of the following.

1. (18 ft) (290 lb)/4.6 s

2. (18.5 kg) (4.65 m)/19.5 s

3. 4500 mi/12.3 h

4. 48.9 kg (1.5 m) (3.25 m)

5. (48.7 m) (68.5 m)/18.4 m)/(35.5 m) (40.0 m)

6. ½(270 kg) (16.4 m/s)²

7. (85.7 kg) (25.7 m/s)²/12.5 m

8. (45.2 kg) (13.7 m)/(2.65 s)²

9. 4/3π (13.5 m)³

10. 140 g/(3.4 cm) (2.8 cm)/(5.6 cm)

11. (213 m) (65.3 m) – (175 m)(44.5 m)

12. (4.5 ft) (7.2 ft) (12.4 ft) + (5.42 ft)³

13. (125 ft) (295 ft)/44.7 ft + (215 ft)³/(68.8 ft) (12.4 ft) + (454 ft)³/(75.5 ft)²

14. (12.5 m) (46.75 m) + (6.76 m)³/4910 m + (41.5 m)(21 m) (28.8 m)/31.7 m
