A car covered the first 400 m distance with a speed of 8 m/s, the next 1200 m with a speed 12 m/s and the last 360 m with a speed of 12 m/s. Calculate the average speed of the car.

10.89

Step-by-step explanation:

The total distance traveled is 1960 m.

400 + 1200 + 360 = 1960

Now, you have to find the time it took to travel each distance.

400 ÷ 8 = 50

1200 ÷ 12 = 100

360 ÷ 12 = 30

The total time it took travel the distance is 180 s.

50 + 100 + 30 = 180

To find the average speed, divided the total distance traveled by the total time.

1960 ÷ 180 = 10.89 s

hey there!

12 is twice as much as 6 because 6 goes into 12 2 times.

since the rabbit is twice as tall, we should multiply the weight of the first rabbit, 0.25, by 2.

0.25 x 2 = 0.5

therefore, the 12 inch chocolate rabbit weighs 0.5 lb, or half a pound.

hope this !

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
