Answer»

Answer:

Total distance = 104 km

AVERAGE speed = 20.8 km/hr

Step-by-step explanation:

GIVEN :

  • Object MOVES with a speed of 16 km/hr for two hours

  • Object moves with a speed of 24 km/h for next three hours

To find :

  • Average speed

Distance = speed×time

Distance travelled in the first interval = 16×2

Distance travelled in the first interval = 32 km

Distance travelled in the second interval = 24×3

Distance travelled in the second interval = 72 km

Total distance distance = 72+32 = 104 km

The total distance covered by the car is equal to 104 km

Average speed = total distance / total time

Total time = 2+3 = 5 hours

Average speed = 104/5

Average speed = 20.8 km/hr

The average speed of the car is equal to 20.8 km/hr
