Will give brainliest, pleassssseee help! Kira is running a race. She runs for 11.2 miles at a speed of 7 miles per hour. for how many hours did she run?

Answer 1

If she runs 7 miles every hour and runs a total of 11.2 miles, we can set this up as:
$11.2=7x$

Where x represents the # of hours she ran for. Let's solve for x:
$x = \frac{11.2}{7} = 1.6$

So, she ran for a total of 1.6 hours.
