Answer:

a) 10 y = x

b) 8.5 min

Step-by-step explanation:

a) x - axis = distance

y - axis = time

the line passing through points (10,1) (20,2) (30,3).......

line equation is y - y1 = m (x - x1)

m = (y2 -y1) / (x2 - x1)

= (2 - 1) / (20 - 10)

m = 1/10

y - 1 = 1/10 * (x - 10)

10(y - 1) = x - 10

10y - 10 = x - 10

10y = x

here x represents distance

y represents time

b) for distance of 85 inches

time =

10 * time = 85

time = 8.5 min
