Question

An object travels 4/5 miles in one half hour. What is its speed?

Answer 1

So,

If you mean "speed per hour," then we just have to double the numerator of the fraction.
4 * 2 = 8

The object's speed is 8/5 miles per hour or 1.6 mph.

Answer 2

By definition, the speed of an object is given by:

`image`

Where,

d: distance traveled by the object

t: time it takes the object to travel the distance

Substituting values we have:

`image`

`image`

Answer:

The speed of the object to travel 4/5 miles in half an hour is:

`s = (8)/(5) mph`
