Answer:
Here is a few answers, it depends on which form you need.
Step-by-step explanation:
Using the speed - time relation, the distance between point A and B is 6000 cm
Recall :
- Distance = speed × time
- Time = distance / speed
Let ; the time taken = t ; distance = d
<u>To trip</u> :
<u>Fro trip</u> :
- t is in seconds ; 15 minutes = (15×60) = 900 seconds
d = 2.5(t + 900)
d = 2.5t + 2250 - - - - - (2)
Equating (1) and (2)
4t = 2.5t + 2250
Collect like terms
4t - 2.5t = 2250
1.5t = 2250
t = 2250 / 1.5
t = 1500 seconds
Hence, distance = 4(t) = 4(1500) = 6000 cm
Therefore, the distance between the points is 6000 cm

Answer:
x = -1
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-2*(x-5)+7-(19)=0
Step by step solution
Equation at the end of step 1
((0 - 2 • (x - 5)) + 7) - 19 = 0
Pulling out like terms
3.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
Equation at the end of step
3
-2 • (x + 1) = 0
STEP
4
Equations which are never true
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
