SchwarzschildRadius

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.

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


\(s = \frac{d}{t}
\)

Where,

d: distance traveled by the object

t: time it takes the object to travel the distance

Substituting values we have:

\(s =\frac{\frac{4}{5}}{\frac{1}{2}}
\)

\(s = \frac{8}{5} mph
\)

Answer:

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

\(s = \frac{8}{5} mph\)
