Answer:
319 miles
Step-by-step explanation:
First, we need to calculate the average speed of the truck. So, we know that the truck traveled 232 miles in 4 hours ( from 1:00 p.m. to 5:00 p.m.). Then, the average speed is:
So, we know that the truck travel 58 miles every hour.
Now, we need to find how many miles the truck traveled after 5.5 hours (from 1:00 p.m. to 6:30 p.m.). Therefore, the number of miles can be calculated as:
So, the answer is 319 miles.
