Final answer:
To calculate the total distance traveled, we need to find the distance traveled in each segment of the trip and add them up. The car traveled a total of 31 km for the entire trip.
Step-by-step explanation:
To determine the distance traveled for the entire trip, we need to calculate the distance traveled during each segment of the trip and then add them up.
First, we calculate the distance traveled at a speed of 40 km/h for 15 minutes. Since speed is the distance traveled per unit of time, we can use the formula distance = speed × time. So, the distance traveled in this segment is 40 km/h × (15 min ÷ 60 min/h) = 10 km.
Next, we calculate the distance traveled at a speed of 60 km/h for 20 minutes. Following the same formula, we find that the distance traveled in this segment is 60 km/h × (20 min ÷ 60 min/h) = 20 km.
Finally, we calculate the distance traveled at a speed of 10 km/h for 6 minutes. Using the formula, we find that the distance traveled is 10 km/h × (6 min ÷ 60 min/h) = 1 km.
Adding up the distances traveled in each segment, the car traveled a total of 10 km + 20 km + 1 km = 31 km for the entire trip.
