Driving from Tulsa to Detroit, Takimi average 50mph, he figured thatnif he had average 60mph his driving hours would have decreased 3 hrs. How far is it from Tulsa to Detroit?
distance = rate*times
d=50*t
also
d=60*(t-3)
set both equation equal to each other:
50*t=60(t-3)
solve for t
t= 18 hours
so plug t into either equation to get distance
50*18 = 900miles
