How long would it take a Bike Traveling 70mph to go 250 yards

7.3 seconds

At that speed it is travelling at 77 feet per second. Almost 26 yards per second so the answer is 9.3 seconds

Given the international mile is 5280 feet (1760 yards) then at 70 mph you are doing 123200 yards an hour. This factors down to 2053.33333 yards per minute or 34.22222 yards per second.

Therefore to cover 250 yards you will take 7.3051948.. seconds.

Just under 10 seconds

l will let you figure it out, but with help.
60 mph=88 feet per second, multiply by 7/6 to get 70 mph, and you get 102.66667 fps.
250 yds= 750 ft
so 750 ft/102.66667 f/s gives you 7.305 seconds.
So it takes 7.31 seconds to travel 250 yds at 70 mph.
l guess l did give you the answer.
It is a good starting point to remember that 60 mph is 88 ft per second.
Good luck.

9.94 secs on a flying run.

70 mi/hr = 103 ft/sec

So ppls getting 7.3 secs are right, do not know how
anybody got 9.6 or whatever.

l am usually too busy watching the road to think about it.
