Answer:
Number of minutes per lap = 2.25 minute
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 33.75 minutes
Step-by-step explanation:
Given:
Number of laps = 4
Time taken = 9 min
Computation:
Number of minutes per lap = 9 / 4
Number of minutes per lap = 2.25 minute
Number of lap per minute = 4 / 9
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 15 x 2.25
Time taken for 15 lap = 33.75 minutes
Answer:
C. Use properties of equality to get the variable on one side of the equation and constant terms on the other.
Step-by-step explanation:
In solving an equation, It is true that properties of equality should be used by putting the variable on one side and the constant on the other side.
Now let use an example to drive this;
Given:
2x - 9 = x + 8
This is an equation, and what we have on both sides should be equal.
Collect like terms;
2x - x = 8 + 9
x = 17
So the solution is 17.
This is the best way to solve an equation.
440??
300+(14 tens=140) 140= 440
You never gave the speed of the blue train.
The path to collision is equal to 1½ circles.
1.5 x 210 meters
= 315 meters
I'm going to arbitrarily guess the speed of the blue train is 15 meters per minute. They are therefore approaching each other at a combined rate of 35 meters per minute.
315 / 35 = 9 minutes
Answer:
9 minutes
Answer:
An arrow goes from 0 to negative 3 and from negative 3 to negative 4.5
Step-by-step explanation:
Start at 0 and move 3 units to the left since it is negative
Move 1.5 units to the left since we are subtracting
We end up at - 4.5
