Answer:
30 km/h
Step-by-step explanation:
usual speed= x km/h
increased speed= x +10 km/h
distance= 360 km
time difference= 3 h
- 360/x= 360/(x+10) +3
- 360/x= (360+ 3x+30)/(x+10)
- 360(x+10)= x(390+3x)
- 360x+3600= 390x+ 3x²
- 3x² + 30 x -3600=0
- x²+10x-1200=0
- x=30 km/h
Answer:

Step-by-step explanation:
Given:
Number of boxes fill = 6,021
Time is taken = 0.9 hour
Find:

Explanation:</h2>
As I understand the question, you need the distance between the numbers -2 and 1.5. In order to find this result, let's put these numbers in a number line as indicated below.
To find the distance, set a point on -2 and count how many units you can walk in order to get 1.5, so the result is 3.5 units. Also, this can be written as the following expression using absolute values:
