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#
no problem. Average speed is
total distance / total time:
(45+20)km/(3 + 3/2 + 3/2)hr = 65/6 km/hr
To find the average speed, we need to divide the total distance traveled by the total time taken.
First, let's calculate the total distance traveled:
Distance from town A to B = 45 km
Distance from town B to C = 20 km
Total distance = 45 km + 20 km = 65 km
Next, let's calculate the total time taken:
Time taken from town A to B = 3 hours
Rest time = 1 hour
Time taken from town B to C = 1 hour
Total time = 3 hours + 1 hour + 1 hour = 5 hours
Now, divide the total distance by the total time to get the average speed:
Average Speed = Total Distance / Total Time
Average Speed = 65 km / 5 hours = 13 km/hour
Therefore, the average speed Ali rode was 13 km/hour.
