1 hr = 3600 seconds
.
26 miles/hr = 26 miles/1 hr = 26 miles/3600 seconds = .0072222 miles/second
.
.82 seconds * .0072222 miles/sec = .0059222 miles
.
That is not a very help measure, but we can multiply by 5280 ft/mile to get a better answer.
.
5280 ft/mile * .059222 miles = 31.2693 ft
.
As a quick reasonableness check, in school I memorized that 60 mi/hr = 88 ft/sec.
So in round numbers, 26 mph is about 30 mph = about 44 ft/sec.
And .82 is about .75 or 3/4 of a second.
3/4 of 44 = 33
.
Answer:
The car travels about 31.2693 ft in .82 seconds at 26 mph.
.
Done
