The distance a race car travels is given by the equation d=v0t+12at2 where v0 is the initial speed of the race car, a is the acceleration, and t is the time travelled. Write an equation for the driver's average speed s during the acceleration. (Hint: Average speed is equal to distance divided by time.)

The average speed s (technically average velocity) at time t will be given by the equation:

Given that:

If d denotes the distance travelled by the car with initial velocity and acceleration a, then:

And since average speed is total distance divided by total time taken, thus let the average speed is denoted by s, then:

The terms speed and distance here, are technically referring to the terms velocity and displacement respectively since speed and distance are scalar quantities.

v0 + 1/2at

Step-by-step explanation: Given that the distance a race car travels is given by the equation d = v0t+12at2 where v0 is the initial speed of the race car, a is the acceleration, and t is the time travelled.

The equation for the driver's average speed s during the acceleration will be:

(v0t+12at2) / t

Since Average speed is equal to distance divided by time.

Therefore, the equation will be:

v0+1/2at

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
