Concept explainers
(a)
The conversion factor between km/h and mi/h.
(a)
Answer to Problem 20P
The conversion factor is
Explanation of Solution
Given:
The given unit are, km/h and mi/h
Formula used:
1 mile = 1.6 km
Calculation:
Since 1 mile = 1.6 km
So,
Conclusion:
Thus, the conversion factor is
(b)
The conversion factor between m/s and ft/s.
(b)
Answer to Problem 20P
The conversion factor is
Explanation of Solution
Given:
The units are ft/s and m/s
Formula used:
1 ft = 0.3048 m
Calculation:
Since 1 ft = 0.3048 m
So,
Conclusion:
Thus, the conversion factor is
(c)
The conversion factor between km/hr and m/s.
(c)
Answer to Problem 20P
The conversion factor is
Explanation of Solution
Given:
The units are km/hr and m/s
Formula used:
1 km = 1000 m
1 hr = 3600 s
Calculation:
Since 1 km = 1000 m and 1 hr = 3600 s
So,
Conclusion:
Thus, the conversion factor is
