Answer:

1.25 miles per hour

Step-by-step explanation:

For this problem, we simply need to understand what a rate is.  A rate is an expression of a relation between two quantities.   In this case, our rate will be miles per hour, since we are given a distance, 10 miles, and a duration, 8 hours.  Let's use this formulate

Rate = Distance / Time

Now let's find Elijah's walking rate by plugging in our values into the formula above.

Rate = Distance / Time

Rate = 10 miles / 8 hours

Rate = 5 miles / 4 hours

Rate = (5 / 4) miles per hour (mph)

So, Elijah's walking rate is 5/4 mph.  Let's convert this fraction into a decimal.  5/4 is equal to 1.25.

Hence, we can say Elijah's walking rate is either 5/4 mph or 1.25 mph.

Cheers.
