Step-by-step explanation:
1. The situation after 15 min:
(a) Distance travelled by simulated biker:
15 min =¼ h

(b) Distance travelled by Julian
Julian is 2¼ km behind the biker. The distance he has travelled is (5 - 2¼) km
5 - 2¼ = 5 - ⁹/₄ = ²⁰/₄ - ⁹/₄ = ¹¹/₄ = 2¾
Julian has travelled 2¾ km in ¼ h.
2. Julian's average speed

47- 12 1/3 = 34 2/3
He needs 34 and 2/3 feet more of fabric
