Solution
Solution Steps
Step 1: Convert Base Depth from Centimeters to Inches
Use the conversion factor: \(1 \, \text{cm} = 0.393701 \, \text{inches}\).
Multiply the base depth in centimeters by the conversion factor:
\[
120 \, \text{cm} \times 0.393701 \, \text{inches/cm} = 47.24412 \, \text{inches}
\]
Round the result to the nearest inch: \(47 \, \text{inches}\).
Step 2: Convert Temperature from Celsius to Fahrenheit
Use the conversion formula: \(F = \frac{9}{5}C + 32\).
Substitute the given temperature in Celsius:
\[
F = \frac{9}{5} \times (-12) + 32
\]
Calculate the result:
\[
F = -21.6 + 32 = 10.4
\]
Round the result to the nearest degree: \(10^{\circ} \, \text{F}\).
Step 3: Convert Wind Speed from Kilometers per Hour to Miles per Hour
Use the conversion factor: \(1 \, \text{km/h} = 0.621371 \, \text{mph}\).
Multiply the wind speed in kilometers per hour by the conversion factor:
\[
10 \, \text{km/h} \times 0.621371 \, \text{mph/km/h} = 6.21371 \, \text{mph}
\]
Round the result to the nearest mile per hour: \(6 \, \text{mph}\).
