Hi. Question is incomplete. We need to find the Total displacement of the body.
∴ Time = 15 min. = 15 × 60 seconds = 900 seconds.
Average Velocity = 12.5 km/hr = 12.5 × 5/18 = 3.47 m/s.
∴ Displacement = Velocity × time.
⇒ Displacement = 3.47 × 900
= 3125 m.
Hence, total displacement is 3125 m. or 3.125 km.
Hope it helps.
