Ali rode a bicycle from town A to town C through town B as follows.He rode from A to B a distance of 45 km in 3 hours and then rested for 1hr and 1/2 hr.From B he rode to C a distance of 20 km in 1hr and 1/2 hr. Find the average speed riding
#Please guys help me out this question#
d = 45 + 20 = 65 km.
t = 3 + 1.5 + 1.5 = 6.0 Hours.
V = d/t = 65km/6h = 10.83 km/h.
To find the average speed riding, we need to calculate the total distance traveled and the total time taken.
1. Calculate the total distance:
Ali rode a distance of 45 km from town A to town B, and then another distance of 20 km from town B to town C. Therefore, the total distance is 45 km + 20 km = 65 km.
2. Calculate the total time taken:
Ali took 3 hours to ride from town A to town B and then rested for 1 hour and 1/2 hour. So the total time taken for the first leg of the journey is 3 hours + 1 hour + 1/2 hour = 4.5 hours.
Then, Ali took 1 hour and 1/2 hour to ride from town B to town C. So the total time taken for the second leg of the journey is 1 hour + 1/2 hour = 1.5 hours.
Now, we can calculate the total time taken for the whole journey by adding the time taken for both legs: 4.5 hours + 1.5 hours = 6 hours.
3. Calculate the average speed:
To find the average speed, we divide the total distance by the total time taken:
Average speed = Total distance / Total time
Average speed = 65 km / 6 hours
Therefore, the average speed riding is 10.83 km/h (rounded to two decimal places).
