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

Answer 1

" constant velocity "

you don't need calculus

Answer 2

ok so how would i solve it?

Answer 3

you can if you wanna

Answer 4

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

Answer 5

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

Answer 6

or 15(20) :)

Answer 7

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

Answer 8

im trying to find the distance traveled not the velocity

Answer 9

i know, and i did it 2 ways

Answer 10

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

Answer 11

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

Answer 12

ohh because distance=rate times time?

Answer 13

yes
