In distance word problems, times is measured in miles per hour not minutes.
This means we need to convert hours to seconds.
We also need to use the formula D = rt, where D = distance, r = rate or speed and t = time in hours and then solve for t.
100 = 35t
Solving for t, we get 100/35 = t.
We now convert 100/35 hours to seconds.
100/35 in terms of seconds is about 10285.714285714

Convert miles/hr to ft/sec
(mi/hr)x(ft/mi)x(hr/sec) = ft/sec
35 mi/hr x 5280 ft/mi x 1%2F3600hr/sec
35%2A5280%2A1%2F3600+=+51.333 ft/sec
d+=+r%2At
t+=+d%2Fr
t+=+100%2F51.333 sec
t+=+1.95 sec
About 2 sec
