A bus travel 250km south along a straight path with the average velocity of 84km/h to the the bus stop for 26 min. Then in it travel 240km with avrage 70km/h to the south.How long long did the hold trip take? What is the average velocity of the trip?
The total trip on the bus took 6.66 h
The average velociity was 60km/h
To find out how long the entire trip took, we need to calculate the time taken for each leg of the journey and add them together.
For the first leg of the journey, the bus travels 250 km at an average velocity of 84 km/h. We can use the formula: time = distance / velocity.
Time taken for the first leg = 250 km / 84 km/h = 2.98 hours (rounded to 2 decimal places)
For the second leg of the journey, the bus travels 240 km at an average velocity of 70 km/h.
Time taken for the second leg = 240 km / 70 km/h = 3.43 hours (rounded to 2 decimal places)
Now, we need to add the time taken for both legs to find the total time taken for the entire trip.
Total time taken = 2.98 hours + 3.43 hours = 6.41 hours (rounded to 2 decimal places)
Therefore, the entire trip took approximately 6.41 hours.
To find the average velocity of the entire trip, we need to calculate the total distance traveled and divide it by the total time taken.
Total distance traveled = 250 km (first leg) + 240 km (second leg) = 490 km
Average velocity = total distance / total time taken
Average velocity = 490 km / 6.41 hours = 76.38 km/h (rounded to 2 decimal places)
Therefore, the average velocity of the trip is approximately 76.38 km/h.
