$Speed = Distance / Time$

Here, Total Distance = $3 m$

And, Total Time = $0.3 s$

then, The Overall Speed is = $\frac{3}{0.3} = 10 m/s$

Simple use $v = \frac{s}{t}$ Put the value as $s = 3$ and $t = 0.3$ Simplify, and get- $v = \frac{3}{0.3} = \fbox{10}.$

1. the car is 3 meters long
2. if the rear of the car is under the light 0.3 seconds after the front of the car, the car is traveling 3 meters every 0.3 seconds, or 1 meter every tenth of a second.
3. If the car is constantly traveling 1 meter every tenth of a second, then the car will travel 10 meters in one second.

the constant speed of the car is 10m/s

Using the formula $d=rt$ , we have $3=0.3r\iff\frac{3}{0.3}=r\iff\boxed{10=r}$

RTF: Speed Given: Distance = 3 meters Time = 0.3 seconds Using the formula for speed

Speed = $\frac{Distance}{Time}$ = $\frac{3}{0.3}$ = 10 $\frac{m}{s}$

given D=3m T=.3s V=D/T then V=3/.3=10

V=S/T V=3,0/0,3 V=10 m/s

the question is asking the velocity of a car..the formula for velocity is D/T where d=distance and T=time so d= 3 meter T= 0.3 so...D/T=3/0.3=10 m/sec.

De acordo com o enunciado temos:

$\begin{cases} S = 3 \; m \\ t = 0,3 \; s \\ v = \end{cases} \\\\ S = v \cdot t \\ 3 = 0,3t \\\\ \frac{3t}{10} = 3 \\\\ \boxed{t = 10 \; m/s}$

Lenght of Car=3 m Time=0.3 s v=? Solution; S=v/t v=St v=3(0.3) v=0.9=10

speed=distance/time =3/0.3 =10

Here is my solution.

v = s/t v = 3/0.3 v = 10
