Poetry uses forms and conventions to suggest differential interpretation to words, or to evoke emotive responses. Devices such as assonance, alliteration, onomatopoeia and rhythm are sometimes used to achieve musical or incantatory effects.
The average speed of an object tells you the (average) rate at which it covers distance. If a car's average speed is 65 miles per hour, this means that the car's position will change (on the average) by 65 miles each hour.
Boy, this is easy!. Unfortunately, however, the answer is not 90 miles/hour. Here's why: You know that average velocity = distance/time (v = d/t). In order to have an average speed of 60 miles/hour over a distance of 60 miles, you must complete the trip in 1 hour:But Susie has already taken an hour (it takes 1 hour to go 30 miles with an average speed of 30 miles/hour) - and she is only half way!f a car's average speed is 65 miles per hour, this means that the car's position will change (on the average) by 65 miles each hour. Average speed is a rate. In kinematics, a rate is always a quantity divided by the time taken to get that quantity (the elapsed time).
