Question

The posted speed limit is 45 miles per hour. Choose all the metric measures that are faster than 45 miles per hour. Customary and Metric Unit Equivalents DATA Length Weight/Mass Capacity 1 m - 3.28 ft 1 Oz - 28.35 g 1 gal - 3.79 L 1 m - 39.37 in. 1 kg - 2.20 lb 1 gt - 0.95 L 1 in. - 2.54 cm 1 metric ton (1) - 1.102 T 1 mi - 1.61 km A 45 km per hour B. 64.1 km per hour C. 86.4 km per hour D. 91 km per hour E. 112.3 km per hour

Answer 1

Converting 45 miles/hour to km/h, we have:

$45\frac{miles}{h}\cdot(\frac{1.61\frac{\operatorname{km}}{h}}{1\frac{\text{miles}}{h}})=72.45\text{ km/h}$

Metric measures that are faster than 45 miles/hour = C. 86.4 km per hour / D. 91 km per hour / E. 112.3 km per hour​
