A car is traveling at a speed of 95 mi/h. If there are 0.62137 miles (mi) in a kilometer,
what is the speed of the car in m/s?

Respuesta :

Answer:

42 m/s

Explanation:

To we convert units for speed we can use dimensional analysis. First thing we do is seperate the measurement into a fraction. After this we can multiply by 1km over 0.62137 miles. We do this so that the miles cancel out.

[tex]\frac{95mi}{h}[/tex] × [tex]\frac{1km}{0.62137mi}[/tex] = [tex]\frac{95km}{0.62137h}[/tex]

After this we can use a conversion factor and divide by 3.6.

[tex]\frac{95km}{0.62137h}[/tex] ÷ 3.6 = 42 m/s
