the tortoise can walk 1/2 mile in 1/4 of an hour. The hare can run 11/2 mile in half an hour. What is the distance

Shalnov [3]

Answer:

The speed of tortoise is 2 miles per hour and

The speed of hare is 11 miles per hour

Step-by-step explanation:

Given as :

The distance cover by tortoise = $\frac{1}{2}$ miles

The Time taken by tortoise to cover distance = $\frac{1}{4}$ hour

So, The speed of the tortoise is = $\dfrac{\textrm Disatnce cover by tortoise}{\textrm time taken}$

I.e The speed of the tortoise = $\frac{\frac{1}{2}}{\frac{1}{4}}$

∴ The speed of the tortoise = 2 miles per hour

Again ,

The distance cover by hare = $\frac{11}{2}$ miles

The Time taken by hare to cover distance = $\frac{1}{2}$ hour

So, The speed of the hare = $\dfrac{\textrm Disatnce cover by hare}{\textrm time taken}$

I.e The speed of the hare = $\frac{\frac{11}{2}}{\frac{1}{2}}$

∴ The speed of the hare = 11 miles per hour

Hence The speed of tortoise is 2 miles per hour and

The speed of hare is 11 miles per hour . Answer
