At 08 20, Tiffany left Town D and cycled towards Town E. Pamela left Town D and cycled towards Town E at 08 50. Pamela's cycling speed was 2 km/h faster than Tiffany. At 14 20, Pamela caught up with Tiffany. Find the cycling speed of each cyclist.

1. Tiffany
2. Pamela

(a)
Duration that Pamela cycled from 08 50 to 14 20
= 5³⁰₆₀
= 5¹₂ h

Distance that Pamela cycled more than Tiffany
= 5¹₂ x 2
= 11 km

However, since Tiffany left 30 minutes earlier than Pamela and Pamela caught up with Tiffany, it means that Tiffany has cycled 11 km in 30 min.

1 h = 60 min 
30 min = 30 ÷ 60 = ¹₂ h

Tiffany's cycling speed
= 11 ÷ ¹₂
= 11 x ²₁
= 22 km/h

(b)
Pamela's cycling speed
= 22 + 2
= 24 km/h

Answer(s): (a) 22 km/h ; (b) 24 km/h
