Answer :
The average speed of the truck is approximately 84.6 km/h.
To find the average speed of the truck, you need to use the formula for average speed, which is given as:
average speed = total distance / total time
We know that the truck travels for 32.9 minutes at a speed of 58.3 km/h.
Therefore, the distance covered by the truck in this time is given by: distance1 = speed1 × time1
= 58.3 km/h × (32.9 minutes / 60 minutes)
= 32.03 km
Similarly, for the next 52.7 minutes, the distance covered by the truck is given by:
distance2 = speed2 × time2
= 97.3 km/h × (52.7 minutes / 60 minutes)
= 88.68 km.
Therefore, the total distance covered by the truck is:
total distance = distance1 + distance2
= 32.03 km + 88.68 km
= 120.71 km
The total time taken by the truck to cover this distance is:
total time = time1 + time2
= 32.9 minutes + 52.7 minutes
= 85.6 minutes.
Now, substituting the values of total distance and total time in the formula for average speed, we get:
average speed = total distance / total time
= 120.71 km / (85.6 minutes / 60 minutes)
≈ 84.6 km/h.
Therefore, the average speed of the truck is approximately 84.6 km/h.
