Dominique drove home from work at an average speed of 36 miles per hour. if the distance from her house to her workplace is 5.4 miles, how long did her commute take?

Dominique's commute took 9 minutes

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Since we are given 3 values with 1 variable, and this is a ratio problem we can use the Rule of Three technique to calculate how long her commute will take. The technique is shown in the picture attached below, but before we can use this technique we need to change the hours into minutes.

1 hour = 60 minutes

Now we can use the technique...

36 miles   ⇒   60 minutes

5.4 miles   ⇒   x

Finally, we can see that it to Dominique's commute took 9 minutes.

I hope this answered your question. If you have any more questions feel free to ask away at .
