Step 1

(a) The difference between the distances travelled by tortoise and hare is equal to 40 cm. Distance can be expressed as the product of speedand time. The variables that are to be used are - distance travelled by tortoise *d*_{t} , distance travelled by hare *d*_{h} ,time taken for tortoise *t* and speed of tortoise *v*. Speed of hare is 20*v*.

Step 2

Substituting the given values and re-arranging,

Step 3

(b)The expression for length of the race is equal ...
