Given:

A man travels from A to B at 4 km/h and from B to A at 6 km/h

Total time taken = 45 minutes

Formula:

Speed = Distance ÷ Time

60 minutes = 1 hour

So, To convert minutes to hour Divide it by 60,

= 45/60 = 3/4 hour

Let the distance between point A to B be x

So, According to question

x/4 + x/6 = 3/4

6x + 4x/24 = 3/4

4(10x) = 24(3)

40x = 72

40x/40 = 72/40

x = 1.8 km

Thus, The distance travelled by the man from point A to B is 1.8 km
