The distance between Town V and Town W was 176 km. At 06 00, Opal left Town V and cycled towards Town W. Cindy left Town V and cycled towards Town W at 06 30. Cindy's cycling speed was 2 km/h faster than Opal. At 12 00, Cindy caught up with Opal. When Cindy was 22 km from Town W, she stopped to wait for Opal. How far was Opal from Cindy when she stopped to wait for him?
Duration in which Cindy cycled for before she caught up with Opal
= from 06 30 to 12 00
= 5 h 30 min
= 5 ³⁰₆₀ h
= 5 ¹₂ h

Distance that Cindy cycled more than Opal
= 5¹₂ x 2
= ¹¹₂ x 2
= 6 km

Opal's cycling speed
= 6 x 2
= 12 km/h

Cindy's cycling speed
= 12 + 2
= 14 km/h

Distance that Cindy cycled before she stopped to wait for Opal
= 176 - 22
= 154 km

Duration that Cindy cycled for after she caught up with Opal and when she stopped to wait for Opal
= (154 ÷ 14) - 5¹₂
= 11 - 5¹₂
= 5¹₂ h

Distance Opal was from Cindy when she stopped to wait
= 2 x 5¹₂
= 11 km

Answer(s): 11 km
