MMMMD or as D(V) D(V) = -500+1000*5 = 4500
In roman numerals, numbers greater than 3999 use parentheses around, or a horizontal line above, the numbers that are multiplied by 1000. Writing 3999 is written as MMMCMXCIX, but the number 4500 would be written as (IV)D.
The answer is 514.d=500 x=10 iv=4500 + 10 + 4 = 514
The accepted convention does not permit values over MMMCMXCIX (3999) to be notated in Roman numerals (the letter M cannot be repeated more than 3 times). Breaking with convention, MMMMD would be 4500. In the middle ages, an overline would multiply the value by 1,000, while vertical lines either side of a numeral multiplied the numeral by 100. Using that convention, we could represent 4500 as 45 * 100 which would be |VL|
14.8 m/s is the velocity, 4.5 * 10^3m is the distance, correct? 4.5 * 10^3 is the same as 4500 m. V=D/T where V is velocity, D is distance, and T is time. To get your answer, plug in what you know into the equation. 14.8=4500/t. You need to get the T by itself, so multiply both sides of the equation by T to get 14.8T=4500, then divide both sides by 14.8 to get the T alone. you end up with T = 304.054. the time measurement is in seconds.
