instantaneous velocity at a pont on D-T diagram is given by the slope of the curve at that point from the graph you will observe that B to Q the vehicle have same velocity means have same slope find the slope of BQ which is equal to the QR/PR QR is 5 km = 5000m PR is 15minutes = 900 sec we get velocity is 5000/900 = 5.55 m/sec
