Answer 1

Answer:

(7) - 36

(8) - 18

Step-by-step explanation:

(7)

60 minutes = 54 km

1 minute = (54/60)

40 minutes = (54/60) * 40

                   = 36 km.

Therefore,distance = 36 km.

(8)

Let the third proportion be x.

Hence, 8/12 = 12/x

⇒ 8x = 12 * 12

⇒ 8x = 144

⇒ x = 18.

Therefore, the third proportion is 18.

Hope it helps!
