At 08 35, Victoria left Town V and cycled towards Town W. Emily left Town V and cycled towards Town W at 08 50. Emily's cycling speed was 4 km/h faster than Victoria. At 10 35, Emily caught up with Victoria. Find the cycling speed of each cyclist.

1. Victoria
2. Emily

(a)
Duration that Emily cycled from 08 50 to 10 35
= 1⁴⁵₆₀
= 1³₄ h

Distance that Emily cycled more than Victoria
= 1³₄ x 4
= 7 km

However, since Victoria left 15 minutes earlier than Emily and Emily caught up with Victoria, it means that Victoria has cycled 7 km in 15 min.

1 h = 60 min 
15 min = 15 ÷ 60 = ¹₄ h

Victoria's cycling speed
= 7 ÷ ¹₄
= 7 x ⁴₁
= 28 km/h

(b)
Emily's cycling speed
= 28 + 4
= 32 km/h

Answer(s): (a) 28 km/h ; (b) 32 km/h
