speed = distance / time
so time = distance / speed
124 yards = 0.0704545454 miles (1 yard = 0.000568181818 mile)
so time taken to cover 124 yards = 124 yards / 40 miles per hour
= 0.0704545454 miles / (40 miles / hr)
= (0.0704545454 / 40) hr
= (0.0704545454 / 40) * 3600 secs
= 6.34090909 secs

60 seconds/min X 60 min./hour = 3600 sec/hr
3600/40 = 90 sec. to go 1 mile at 40 mph
1 mile = 1760 yds.
124 yds X (90/1760) = 124 X .0511 = 6.34 sec.

9.46 seconds (i think) 1760 yards to a mile x40 mph/60 min. ... this gives you how many yards per min. then divide this by 124=how many secs to cover 124 yards. Does this seem right?

I think max is right...I got the same thing... Or maybe we have the same flawed method...Either way I got the same thing.
