Question 1200497: A bicycle is traveling at 20 miles per hour.
How many feet will it cover in 30 seconds?
Round your answer to the nearest tenth of a foot. Found 2 solutions by math_tutor2020, Theo:Answer by math_tutor2020(3817) (Show Source):
"minutes" units cancel
The only thing left will be "ft" up top and "sec" down below
That gives the speed unit ft/sec aka "feet per second", often abbreviated to fps.
Let's finish up the calculation
which is approximate; the '3's go on forever.
The person biking at 20 mph is moving at roughly 29.33333333 ft/sec
distance = rate*time
distance = (29.33333333 ft/sec)*(30 sec)
distance = 879.9999999
distance = 880 feet is the final answer.
------------------------------------------------
Another approach:
1 hour = 60 min
1 min = 60 sec
Those two equations tell us that
1 hour = 60*60 = 3600 sec
Meaning that 1 second is 1/3600 of an hour.
30 seconds is 30*(1/3600) = 30/3600 = 1/120 of an hour.
distance = rate*time
distance = (20 mph)*(1/120 of an hour)
distance = 20/120 miles
distance = 1/6 of a mile.
Then,
1 mile = 5280 ft
(1/6)*1 mile = (1/6)*5280 ft
1/6 of a mile = 880 feet
You can put this solution on YOUR website! the bicycle is traveling at 20 miles per hour.
20 miles = 20 * 5280 = 105600 feet.
1 hour = 3600 seconds.
the bicycle is therefore traveling 105600 in 3600 seconds.
that's equal to 105600/3600 = 29.333333333... feet per second.
therefore, the bicycle travels 30 * 29.333333333... = 880 feet in 30 seconds.
that's the number of feet the bicycle traveled in 30 seconds.
