The answer is: [A]: 52.5 (mi.)
________________________________________
Explanation:
_________________________
Use the formula: D = r*t .
_________________________
{Note of interest: The formula is not unique to this specific problem; but is actually true and will appear in physics and even advanced math and calculus!).
____________________________________________
In which: D = distance traveled (which we want to solve);
r = rate of travel; which we are given as: "15 mi / h" ;
t = time traveled; which we are given as: "3.5 h" ,
______________________________________________
We want to solve for "D".
______________________
Make sure all the units are equal (which they are!). They are all in "mi." and "hours". And the questions asks for the value in miles
___________________________________
D = r * t ; solve for "D" ; by plugging in our known values of "r" and "t":
____________________________________
→ D = r * t =
* (3.5 h) ;
____________________________________
→ The 2 "h's" cancel out; and we are left with:
______________________________________
→ D = (15 mi.) * 3.5 = 52.5 mi. → which is answer choice: [A].
