For Tortoise Let
D = distance of the race
Rate = 50 ft per hour
T = Time
For Hare:
Rate= 250 per hour
Time =T-8
[ Given The tortoise takes 8 hours longer than the hare to finish
That is time taken by Hare is 8 hours less than Tortoise.]
The standard formula for all constant motion is
D = r * t
Distance covered by Hare and Tortoise is same so we have:
50 * t = 250 * (t-8)
Or 50*t=250 t -2000 ( using distributive rule)
Or,
50t-250t= 250t-250t -2000 ( subtract 250t both sides)
-200t = -2000
t= 10.(Dividing both sides by 200)
D= 50t
Substituting t=10 we have
D= 50(10)
D=500ft.
Distance of race is 500ft.
