Coucou, j'ai besoin d'aide pour résoudre ce problème. Merci d'avance

1. The cities which we are going to cross are :
A = Dover,  B = Rye and C = Brighton

2. If we want to cover the distance in approximately five and half hours, then :

5H30 = 5,5H.
We want to cover a distance of 227 km so 141,08 Miles.

The average speed of our bus (in Mph) must be : 141,08 / 5,5 = 26 Mph
