What is [tex]4.6 \times 10^8 \, \text{cm/min}[/tex] in meters per hour?
A. [tex]2.76 \times 10^8 \, \text{m/h}[/tex]
B. [tex]2.76 \times 10^{10} \, \text{m/h}[/tex]
C. [tex]7.67 \times 10^6 \, \text{m/h}[/tex]
D. [tex]7.67 \times 10^8 \, \text{m/h}[/tex]
Answer (2)
1 m = 100 c m → 1 c m = 0.01 m 1 h = 60 min → 1 min = 60 1 h ======================== 4.6 × 1 0 8 c m / min = 4.6 × 1 0 8 × 60 1 h 0.01 m = 4.6 × 1 0 8 × 0.6 m / h = 2.76 × 1 0 8 m / h A n s w er : A.
The conversion from 4.6 × 1 0 8 cm/min to meters per hour gives 2.76 × 1 0 8 m/h . The correct answer is option A. This conversion involves changing centimeters to meters and minutes to hours, which results in the final rate of motion.
