I can’t find the distance for B!

Answer:
300 m/ min
Step-by-step explanation:
Using the relationship
distance (D) = speed (S) × time (T), then Ahmad's distance is
D = 240 × 10 = 2400 m
Hence Nan King ran a distance 5400 - 2400 = 3000 m
S = [tex]\frac{D}{T}[/tex] = [tex]\frac{3000}{10}[/tex] = 300 m/ min
