The combined seperation speed of Sandy and Jack was
620km ÷ 4 hours
= 155 km/h
Jack's speed was
(155 + 12) ÷ 2
= 83.5 km/h

For every one quarter of the entire distance covered by George, Hamid lagged 18km ÷ 3 = 6km.
So for the entire journey Hamid lagged George by 6km × 4 = 24 km when George completed the journey, and for that distance of 24km Hamid needed 20 min to cover.
In other words in 60 min Hamid could cover 24km × 3 = 72km
Hamid's speed was 72 km/h
