5.46/0.25= 21.84 hope it helps
Distance=speed times time
distance/time=speed
distance=538
time=9 and 15mins
60mins=1hr
15/60=1/4=0.25
time=9.25hr
distance/time=538/9.25=58.162mph
about 58mph
-4 x 9= -36 and the when you add 5 to -36 you get -31. Hope this helps
I believe it is C. a histogram
(if it’s not then sorry)
Proportional because it's a straight line if you follow the graph points and it goes by 5
