I am having trouble finding the hr, min, and seconds with this math problem.

Question

John ran the? 100-m dash with a time of 9.86 sec. If this pace could be maintained for an entire 26-mi ?marathon, what would his time? be? (Notice that 1 m ~ 3.281 ft and 1-mi = 5280 ft.)
His time would be
hr ____
min____
sec_____
(Round the final answer to the nearest integer. Round all intermediate answers to the nearest integer as? needed.)

Answer 1

at a conversion rate of 1m to 3.281 ft then

100m = 328.1 ft

 

Her rate of speed in ft/sec is

(328.1 ft)/(9.86 sec) ≈ 33.2758621 ft/sec

 

the distance she is running is 26 miles at 5,280 ft /mile

= 26(5,280) = 137,280 ft

 

ft/(ft/sec) = seconds

137,280/33.2758621 = 4125.52 seconds

 

4152.53/60 = 68.758549158671 minutes

 

68.758549158671/60 = 1.1459758193 hours

 

.1459758193(60) = 8.758549158671 minutes

 

.758549158671(60) = 45.51294952 seconds

 

1 hour, 8 minutes, 46 seconds

 

Answer 2

1 m = 3.281 ft.

 

100m = 328.1 ft.

 

328.1 ft. in 9.86 sec.

 

1 mile = 5.280 ft.

 

26 miles = 137,280 ft.

 

137,280/328.1 = 418.41

 

418.41(9.86 sec)= 4125.513 sec

 

1 hr. 8 min. 45 sec.
