The distance between Town D and Town E was 124 km. At 05 00, Jade left Town D and cycled towards Town E. Xandra left Town D and cycled towards Town E at 05 30. Xandra's cycling speed was 2 km/h faster than Jade. At 10 00, Xandra caught up with Jade. When Xandra was 28 km from Town E, she stopped to wait for Jade. How far was Jade from Xandra when she stopped to wait for him?
Duration in which Xandra cycled for before she caught up with Jade
= from 05 30 to 10 00
= 4 h 30 min
= 4 ³⁰₆₀ h
= 4 ¹₂ h

Distance that Xandra cycled more than Jade
= 4¹₂ x 2
= ⁹₂ x 2
= 5 km

Jade's cycling speed
= 5 x 2
= 10 km/h

Xandra's cycling speed
= 10 + 2
= 12 km/h

Distance that Xandra cycled before she stopped to wait for Jade
= 124 - 28
= 96 km

Duration that Xandra cycled for after she caught up with Jade and when she stopped to wait for Jade
= (96 ÷ 12) - 4¹₂
= 8 - 4¹₂
= 3¹₂ h

Distance Jade was from Xandra when she stopped to wait
= 2 x 3¹₂
= 7 km

Answer(s): 7 km
