A car is traveling 83.3 kilometers per hour. What is its speed in miles per minute? One kilometer = 0.62 miles.

Leya [2.2K]

Hi. 2fouls! :)

First convert the number from kilometer to miles:
$83.3*0.62$
$=51.646 miles$

Now to find the miles per minutes,divide the miles per hours by 60 (the amount of minutes in an hour.)

$51.646/60$
$=0.860766667$

The car is travelling at a speed of 0.860766667 miles/minute.

Hope this helps.
