Answer:
The average speed will be 85km/h
Explanation:
From the above data we need to calculate the distance travelled in the given period of time.
The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction.
On the basis of the following table, calculate the speed of the car between 9:00 AM to 10:00 AM time interval.
Hence,
Average speed =Total distance / Total time
Which is , (36680 − 36510) / (10.00−8.00)
= (36680 − 36510) / (10.00−8.00)
= 170km / 2h
= 85km/h
Average speed = 85km/h
Hence the average speed will be 85km/h.
