Answer:

displacement = 43.5 km

Explanation:

displacement = velocity * time taken

Here speed is 87 km/hr, which is given in km per hour

So we need to change the given time to hours:

60 minutes = 1 hours

30 minutes = 0.5 hours

Then using the formula lets find displacement:

      displacement = velocity * time taken

      displacement = 87 km/hr * 0.5

      displacement = 43.5 km
