A tortoise and a hare engage in a race. A tortoise can run with a speed of 0.15 m/s. A hare can run 25 times as fast as the tortoise. In the race, they start at the same time; however, the hare being very proud of his much higher speed stops for a nap for 5.0 minutes. The tortoise wins the race by 35 cm. (a) What is the length of the race? (b) How long does the race take?

Respuesta :

Answer:

Explanation:

The speed of hare = .15 x 25 = 3.75 m /s . Let tortoise took t second to complete the race .

Distance traveled by it = .15 t

Distance traveled by hare = .15 t - .35 m

Time taken by hare to complete this distance

=  t - 5 x 60 s

Speed of hare

= Distance / time

( .15t-.35 ) / t - 300 , so

[tex]\frac{.15t-.35}{t-300} = 3.75[/tex]

t = 312.40

= 5 minutes 12.4 seconds

Distance of race

312.4 x speed of tortoise

= 312.4 x .15

= 46.85 m

Answer:

the answer is 30 minutes
