anonymous · Answer

right

superdavesuper · Answer

so what is the question asking then??

anonymous · Answer

it's asking what the line represents, the line that i drew on the graph.  is it ---1)  perfectly vertical, perfectly horizontal, diagonal or curved

superdavesuper · Answer

ah that makes more sense....so "at a constant speed of 60 mph for a period of 10 hours" what do u think it looks like?

thank you so much.  can i ask u one more ques.  i have a math quiz tomorrow n i am horrible in math

a car moving at 50 miles per hour speeds up steadily to 70 miles per hour over a period of 30 minutes.  how far did it travel during the 30 minute period of acceleration?

superdavesuper · Answer

OK think about it....what is the AVERAGE speed for that 30 minutes? u start at 50 and end up at 70....

anonymous · Answer

20 miles?

superdavesuper · Answer

u start at 50 mile per hour and speed up to 70 mile per hour so the average would be how much?

anonymous · Answer

honestly i just don't know.  sorry if i am a dummy in math

superdavesuper · Answer

well u know how to drive right? think u stepping on ur gas n go from 50 to 70....so ur average speed during that time would be?

anonymous · Answer

i don't drive yet.  lol
