do you use calculus or precalulus to find the distance traveled in 15 sec by an object traveling at a constant velocity of 20 ft/sec

Question

do you use calculus or precalulus to  find the distance traveled in 15 sec by an object traveling at a constant velocity of 20 ft/sec

anonymous · Answer

" constant velocity "

you don't need calculus

anonymous · Answer

ok so how would i solve it?

amistre64 · Answer

you can if you wanna

amistre64 · Answer

20 ft each sec; for 15 secs ....

amistre64 · Answer

20+20+20+20+20+20+20+20+20+20+20+20+20+20+20

amistre64 · Answer

or 15(20) :)

amistre64 · Answer

$$\frac{dv}{dt} = 20$$
$$dv = 20dt$$
$$\int dv =\int_{0}^{t} 20dt$$
$$v=20t|^{t}\text{ ; at t = 15}$$
$$v=20(15)-20(0)$$

im trying to find the distance traveled not the velocity

amistre64 · Answer

i know, and i did it 2 ways

amistre64 · Answer

you "can" use calculus to solve it, but its rather easy to just do the normal stuff

amistre64 · Answer

20 feet per sec for 15 seconds is .... 20 * 15, feet

anonymous · Answer

ohh because distance=rate times time?

amistre64 · Answer

yes
