WILL MEDAL AND FAN

OpenStudy (jeremiahclare):

Calvin's plane is flying at a speed of 600 miles per hour. If y represents the distance the plane has traveled and z represents the time it has spent traveling, which of the following equations shows the relationship between y and z? y = 600 + z z = 600 + y z = 600y y = 600z

OpenStudy (zxcvbnm1216):

what is y's unit? is it hours or minutes?

OpenStudy (jeremiahclare):

idk it does not show anything about minutes or hours

OpenStudy (jeremiahclare):

miles per hour

OpenStudy (jeremiahclare):

i think

OpenStudy (jeremiahclare):

i think its D

OpenStudy (zxcvbnm1216):

If its hour then its y=600z. think of it this way. If you have spent two hours flying. And it goes 600mph then you have travelled 1200mph. If y represents distance than only d works. a would equal 602, b would equal negative number, c would equal a negative number so only d is left

OpenStudy (zxcvbnm1216):

y=600(2)=1200

OpenStudy (jeremiahclare):

ohh cool thxxs

OpenStudy (zxcvbnm1216):
