In order to qualify for finals in racing event,a race car must achieve an average speed of 250km/hr on a track with a total leng

Kazeer [188]

Answer:

The minimum average speed needed in the second half is 270 km/hr

Step-by-step explanation

We can divide the track in two parts. For the first half of the track the average speed the car achieved was 230 km/hr and we need to make sure that the average speed of the full track is 250 km/hr. Then, we can calculate the average speed of the two parts of the track and force this to be equal to 250 km/hr. In equation, defining $v_2$ as the average speed of the second half:

$\frac{230 + v_2}{2}=250$

Solving for $x$

$x=250*2-230\\x=500-230\\x=270$

Therefore, achieving a speed of 270 km/hr in the second half would be enough to achieve an average speed of 250 on the track.
