Please please do not stop making these maths videos - they are such an amazing resource because you explain clearly, without rushing and you're to the point.

I've seen others teaching maths on YouTube who have hundreds of video's but they are not nearly as clear as yours!

[lawanbukaralbarnawi]

A, B, C and D were riding bicycle together at when they arrived at a suspended bridge which they have to cross. They only had one torchlight among the four of them and a torch is essential in crossing the bridge. Atmost two of them can cross the bridge at the same time. A can cross in two minutes, B can cross in three minutes, C can cross in six minutes and D in Nine minutes. When two of them cross together they cross at the pace of the slower person. How should they arrange to cross the bridge in the least possible time?
Justify your answer.
Pls answer. Thank you maa’a
