Distance = rate * time
trip there, 120 = 55 *t
t = 2 and 2/11 hours
trip back, 120 = r * (2.75 - 2.181818181) round trip time - time to get there
120 = r * .568181818181818
r = 211.2 miles per hour
thinking maybe you did not copy the problem accurately...thats pretty fast.
test 1 = 50
test 2 = 70
70+50 = 120
so tests are .5*120/2 = 30 points
hw = .25*100= 25 points
quiz = .25*75 = 18.75
total score = 30+25+18.75 = 73.75
<span>y = 2x - 1 it the answer.</span>
54 l think hope this helps :)
