I think it's in class 6 or something that that start teaching you the logic employed here (Remember? If the train takes 2 hours to travel 100 km, how long will it take to travel 200 km?).
Indeed, high school maths is more advanced than that.
The equation d=rt is taught in 5th class for ICSE, 6th class for CBSE, and 7th class for CIE.
Still at a loss as to what that has to do with the topic of this thread
