How do you do the Q?
Mr A is travelling at 80 Kmph and leaves point X at 815 am, however, Mr B is travelling at 120 Kmph but leaves point Y which is 100 Km further away (behind) from point X at the same time, at what time will Mr B meet Mr A assuming they are travelling in the
Since the angles opposite to the equal sides of an isosceles triangle are equal, we draw a 75 degree angle at R. The point at which the rays from Q and R meet is named P. We will find that PQ = PR.
