To answer the question, convert first the distance of 3000 miles to kilometers by the conversion factor 1 mile is 1.61 kilometer.
                               (3000 mi) x (1.61 km / 1 mile) = 4830 km
The time it would take to travel this distance is the quotient of  distance divided by speed. 
                                   time = 4830 km / (10 km / h) = 483 h
Thus, the answer is 483 hours.

Most of the information's that are given in the question is enough for solving this problem. 
Speed of running = 10 km/h
We already know that
1 mile = 1.60934 kilometer
Then
3000 miles = 4828.032 kilometer
The total distance that needs to be covered = 3000 miles
Then
Number of hours required to cover the distance = 4828.032/10 hours
                                                                            = 482.8 hours
I hope the answer has come to your help.
