Mrs. Scheib was riding her bike and leaves home and rides due east for a distance of 45 km. she returns home on the same bike path. if the entire bike path takes 4 hrs what is her average speed?
Is it 11.25?
Right.
To find Mrs. Scheib's average speed, we can use the formula:
Average Speed = Total Distance / Total Time
Given that Mrs. Scheib rides due east for a distance of 45 km and returns home, the total distance covered is 2 times the distance she rides due east, which is 2 * 45 km = 90 km.
The total time taken to complete the bike path is given as 4 hours.
Therefore, the average speed is:
Average Speed = 90 km / 4 hours = 22.5 km/h
So, Mrs. Scheib's average speed is 22.5 km/h, not 11.25 km/h.
To find Mrs. Scheib's average speed, you need to divide the total distance she traveled by the total time it took her.
In this case, Mrs. Scheib traveled a distance of 45 km east and then returned home, so her total distance is 45 km + 45 km = 90 km.
The total time it took her to complete the bike path is given as 4 hours.
To find her average speed, divide the total distance (90 km) by the total time (4 hours):
Average speed = Total distance / Total time
Average speed = 90 km / 4 hours
Average speed = 22.5 km/h
Therefore, Mrs. Scheib's average speed is 22.5 km/h, not 11.25 km/h.
