While traveling to the office, dolly drives her car at a speed of 60 kmph and then suddenly the car stopped on half of her dista
lisabon 2012 [21]

The average speed of Dolly is 33.33kmph.

Average Speed:

The average speed is defined as the total distance travelled by the object in a particular interval of time. It can be calculated by dividing the total distance travelled by the total time taken.

So, Average Speed = total distance / total time

Here,

Let the total distance is 100 km.

Therefore, consider she will travel 60 km at speed of 60 kmph , 30 km at speed of 30 kmph and 10 km at speed of 10 kmph.

she will required times of 1 hour, 1hour and 1hour

So,

Average speed = 100 / (1 + 1 + 1)

=> 100 / 3 = 33.33

Solve for X.<br> 4(2x + 5) + 2x + 3 = -11
S_A_V [24]
We can begin by rewriting the problem:

4(2x + 5) + 2x + 3 = -11

Let’s solve in steps.

1. Distribute

8x + 20 + 2x + 3 = -11

2. Combine like terms

10x + 23 = -11

3. Subtract 23 from both sides

10x + (23 - 23) = -11 - 23

10x = -34

4. Divide both sides by 10

10 / 10 = 1 (or x)

-34 / 10 = -3.4

Therefore, x = -3.4.
