Can someone please help me? :( ill give brainiest :D

You are correct, c is the answer.

Step-by-step explanation:

Two hot air balloons.

Balloon one: starts at 30 miles from town and after 2 hours, it is 48 miles

Distance of Tasha's balloon is represented by function y = 8x + 20

x is independent variable so it would represent the time.

y is dependent so it represents the miles travelled.

Balloon one = (0, 30) <-- begins here and (2, 48)

Balloon two = (0, 20).

So balloon one began at 30 miles while tasha's balloon began at 20 miles from town.

So Henry's balloon was farther form the town at the beginning.

Now let's find the slope/rate of change and compare then.

Henry's balloon: y-y1/x-x1 = 48-30/2 = 18/2 = 9

Tasha's balloon m: 8

9>8 Therefore henry was faster

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

6 cm
