If a Subway train traveled 12 km in 8 minutes how many km/h was the train going?

1.5 km/h

To find the speed use this:

distance/ time

12/8

90km/h

Step-by-step explanation:

set up as this: 12km/8min = x/60min then cross multiply

12*60 = 720

8*x = 8x

solve for x

720 = 8x

90 = x

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
