There were several occurrences of figurative language. At the very beginning of the poem, the line “We wear the mask that grins and lies” is an example of personification.
If I understand the question right I would believe it to be 5 miles an hour because the course is a mile and he ran a mile in 12 minutes. We know an hour is 60 minutes so we have to divide the number of minutes he is talking from the hour. 60 divided by 12 is 5 so if he is running a mile every 12 minutes then he is running 5mph

The rhyme scheme of the poem is ABAB because the stanza of A (daisy) is the same as C (crazy), and the stanza of B (fly) is the same as D (sky); there are no other sounds introduced at the end in C and D to make more rhymes, but rather they follow the same pattern of the first two stanzas.
