7200 7200 inches = 7200 12 = 600 =\dfrac{7200}{12}=600 feet

We know that

Distance = = Speed × \times Time

Therefore, time taken by Turtle = 600 25 = 24 =\dfrac{600}{25}=24 hours

Time taken by Rabbit = 600 150 + 20 = 4 + 20 = 24 =\dfrac{600}{150}+20=4+20=24 hours

Both \boxed{\text{Both}} of them reached the finished line at the same time

first convert inches into foot 7200/ 12 = 600

turtle at 24h 25x20=500 + 25 x 4 = 100 => 500 + 100 = 600 Rabbit at 24h 150x 4 = 600
