Question

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?

Answer 1

42 m/s

Step-by-step 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.

`(95mi)/(h)` ×
`(1km)/(0.62137mi)` =
`(95km)/(0.62137h)`

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

`(95km)/(0.62137h)` ÷ 3.6 = 42 m/s
