i. Time = 2 hours.
ii. Average speed for the whole journey = 25 km/h
Step-by-step explanation:

The cost of delivering an item that weighs 4/5 of a pound?$21.60.
<h3>How to find the delivery cost?</h3>
Let x = the number of pounds
Thus, we can say that;
Cost = 25x * 1.08
Since we want to find the cost of delivering an item that weighs 4/5 of a pound, the we will put 4/5 for x to get;
Cost = (25 * 4/5) * 1.08
Cost = 20 * 1.08
Cost = 21.6
The delivery cost would be $21.60.
