Heather walked at a rate of 6 miles an hour Use the distance formula d rt to calculate how long it took Heather to walk 5 miles?

Answer 1

I will try to lay it out to show my work:
D=R•T
The distance required to walk is 5 miles, and the rate is 6 mph. That means that there are no unit conversions necessary, so you can just plug them into the equation:
5=6T
Now, you simply solve for T:
5/6=6T/6
T=5/6
Now, you know the amount of time it took was 5/6 of an hour. To make your answer more precise, you need to commence a unit conversion:
5 hours/6 • 60 minutes/1 hour
Then, the hours cancel out, so you get:
5•60 minutes/6
Then, you just solve!
50 minutes
I hope that helped! Once again, your final answer is 50 minutes!
