Answer» Answer: Total distance = 104 km AVERAGE speed = 20.8 km/hr Step-by-step explanation: GIVEN :
To find :
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 |
