Answer 2

When converting all the given speeds to km/h and after comparing them, we have that the greatest is option 2: 10 m/s.

To find which of the given speeds is greatest, we need to convert all the units to km/h so we can compare the values.

• Option 1. 10 km/h

• Option 2. 10 m/s to km/h

$v = 10 \frac{m}{s}*\frac{1 km}{1000 m}*\frac{3600 s}{1 h} = 36 km/h$

• Option 3. 10 ft/s to km/h

$v = 10 \frac{ft}{s}*\frac{1 km}{3280.8 ft}*\frac{3600 s}{1 h} = 11.0 km/h$

• Option 4. 10 mi/h to km/h

$v = 10 \frac{mi}{h}*\frac{1 km}{0.6214 mi} = 16.1 km/h$

• Option 5. 10 yd/s to km/h

$v = 10 \frac{yd}{s}*\frac{1 km}{1093.6 yd}*\frac{3600 s}{1 h} = 32.9 km/h$

Therefore, the greatest speed is option 2: 10 m/s.
