Answer:
8.4 km/hr.
Step-by-step explanation:
We have been given that Julia rides her horse 18 km with a constant speed of 6 km/hr.
Let us find the time taken by Julia to cover a distance of 18 km.



We are also told that she rides another 24 km with a constant speed of 12 km/hr.
Let us find the time taken by Julia to cover a distance of 24 km.



Since we know that
.
Upon substituting our values in above formula we will get,



Therefore, Julia's average speed is 8.4 km per hour.

Select numbers part of the solution
O 4.7 O 5.1 O 7.4 O 8.2 O 9.6
implies that, the value of t cannot exceed 7.4.
So, we have:
4.7, 5.1 and 7.4 in this range
<em>However, 8,2 and 9,6 do not belong to this range</em>
