Answer:
62.15 mi/hr
Step-by-step explanation:
Given:
As both speed limits are given "per hour", we only need to convert 100 km to miles. To do this, set up and solve a ratio for "miles to kilometers", where x is the number of miles to 100 km:
[tex]\implies \sf 1 : 1.609 = x : 100[/tex]
[tex]\implies \sf \dfrac{1}{1.609} = \dfrac{x}{100}[/tex]
[tex]\implies \sf \dfrac{1}{1.609} \cdot 100= x[/tex]
[tex]\implies \sf x= \dfrac{100}{1.609}[/tex]
[tex]\implies \sf x= 62.15040398...[/tex]
Therefore, 100 km/hr = 62.15 mi/hr (2 d.p.)
