The equation for distance id d = st. If a car has a speed of 51 m/s and travels for 13 seconds, how far does it go?

A. 810 m
B. 3.9 m
C. 64 m
D. 663 m

Respuesta :

ANSWER

The correct answer is D. [tex]663m[/tex]

EXPLANATION

The question says how far does it go, meaning we want to find the distance covered.

The equation for distance is

[tex]d=st[/tex]


where [tex]d[/tex] is the distance covered

[tex]s[/tex] is the speed of the car and

[tex]t[/tex] is the time taken.


From the question

[tex]s=51ms^{-1}[/tex] and [tex]t=13s[/tex]


We substitute these values into the formula to get,

[tex]d=51\times13m[/tex]


We carry out the multiplication to obtain,

[tex]d=663m[/tex]


Therefore the correct answer is D
