Recall,
Speed = distance/ time
From the information given, John ran the 100-m dash with a time of 9.95 sec. This means that his speed is
100/9.95 = 10.05 m/s
If this speed is maintained, it means that the speed at which he ran 26 miles is
also 10.05 m/s
We would convert 26 miles to meters. Recall
1 mile = 1609.344 meters
26 miles = 26 x 1609.344 = 41842.944 meters
Time = distance/ speed
Thus, time taken to run 26 mile is
41842.944/10.05
= 4163.48 seconds
we would convert 4163.48 seconds to hours, minutes and seconds.
Recall, 1 hour = 3600 seconds. Thus
4163.48/3600 = 1.1565 hours.
We would convert 0.1565 hours to minutes. We have
1 hour = 60 minutes
0.16 hour = 0.1565 x 60 = 9.39 minutes
We would convert 0.39 minutes to seconds
1 minute = 60 seconds
0.6 minutes = 0.39x 60 = 23 seconds
Thus,
His time would be 1 hr 9 min, 23 sec
