Question

boat a sets of on bearing with velocity 14 km/h boat b sets off bearing 235 with a velocity of 18 km/h calculate the distance between the boats if they have been travelling 2.5 hours

Answer 1

Answer:

distance between boats = 10 km

Step-by-step explanation:

Relative velocity of A wrt B is   $V_{AB}$ = $V_{B}$ - $V_{A}$

                                                          = 18 - 14

                                                          = 4 km/h

Distance between the boats S = $V_{AB}$ x t

                                                   = 4 x 2.5

                                                   = 10 km
