Come on. Change the times to minutes (each hour is 60 min)
then divide each distance by its time....that is the speed of each.
then divide each distance by its time....that is the speed of each.
Dr. Farrar: 13.1mi/2.5h - ----mi/h.
For Mrs. Bishop:
Distance covered = 26.2 miles
Time taken = 4 hours 48 minutes = 4.8 hours (convert minutes to hours by dividing by 60)
Average speed of Mrs. Bishop = Distance / Time taken
= 26.2 miles / 4.8 hours
≈ 5.458 miles per hour
For Dr. Farrar:
Distance covered = 13.1 miles
Time taken = 2 ½ hours = 2.5 hours
Average speed of Dr. Farrar = Distance / Time taken
= 13.1 miles / 2.5 hours
= 5.24 miles per hour
Comparing the average speeds, we can see that Mrs. Bishop had a faster running speed (5.458 miles per hour) than Dr. Farrar (5.24 miles per hour).
Therefore, Mrs. Bishop had the faster running speed.
