Answer:

Option (c) is correct.

The distance covered by the man in 1 hour is represented by te expression $\frac{10}{x}$ miles.

Step-by-step explanation:

Given: A man walks 10 miles in x hours.

We have to choose a correct expression that represents the distance covered by the man in 1 hour.

Consider the given statement."A man walks 10 miles in x hours."

Using UNITARY METHOD,

(is a method in which we first find the value of a single unit and then multiply it with desired quantity)

Distance covered by man in x hours = 10 miles,

So distance covered by man in 1 hour = $\frac{10}{x}$ miles.

So, The distance covered by the man in 1 hour is represented by te expression $\frac{10}{x}$ miles.
