If a car travels 640 miles in 11 hours, what is the average rate (speed) of the car?

The answer is 58.18

Step-by-step explanation:

When we have to determine the speed of an object, we need two informations: total distance and total time of travel that distance. The speed is just an average of distance and time, that is:

So, we have:

distance=640 miles

time= 11 hours

Finally, the average rate of the car is

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.
