Answer:the formula to calculate average speed is :
average speed= total distance/elapsed time .
He drives 5 hours at 55 mph so we need to calculate first how far or the distance he has driven at the moment hence from the above formula d= rt ( r stand for speed and t stand for time while d stand for the distance)
d=rt
d= 55*5= 275 mph this is how far he has driven at the moment.
So to see how many miles left we subtract the miles he has covered to the total miles he has to cover ;
d =665-275= 390
He also want to cover this trip in 11 hours but he has already driven for 5 hours hence time= 11 - 5 = 6 hours left
So now we have d= 390 and t = 6
So now using the same formula we now need to find the average speed which is ' r' in the formula
d = rt
390=r*6
390/6=r
r = 65mph
hence he will have to drive 65 mph to complete his trip in 11 hours.

Answer: The rugged terrain, the fossils of large mammals, and the herd of bison are three things that would make Serena believe she was having a real adventure.
Explanation: Serena didn't seem to be taking the journey seriously, why? because she didn't find her destination particularly interesting. since the vacation didn't excite her. She didn't think there was any reason for her to go outside. Though her buddy insisted that they could have many adventures there, Serena was not finding the trip to be particularly thrilling. Even if she couldn't believe it, she did so after learning about the unforgiving landscape, the presence of fossils, and the sight of a herd of bison.
