Question

Two vehicles leave the same place P at the same time moving along two different roads. One vehicle moves at an average speed of 60 km/hr and the other vehicle moves at an average speed of 80 km/hr. After half an hour the vehicle reach the destinations A and B. If AB subtends 60° at the initial point P, then find AB.

Answer 1

Speed of vehicle A = 60 km/hr

Distance (AP) travelled in half an hour = 60/2 = 30 km

Speed of vehicle B = 80 km/hr 

Distance (PB) travelled in half an hour

= 900+ 1600 – 1200 = 1300
