Total length of 15 car train is 240 centimeters.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, car is 16 centimeters long.
The length of a 15 car train = Length of each car × Number of cars
= 16×15
= 240 centimeters
Therefore, the length of 15 car train is 240 centimeters.

Answer:
BC is 25 units
Step-by-step explanation:
AB = AC
4x + 4 = 6x - 14
4x + 4 - 4x + 14 = 6x - 14 - 4x + 14
18 / 2 = 2x / 2
9 = x
2(9) + 7
18 + 7
25
Answer: BC is 25 units
Answer:
The jet will overtake the plane at 8:25 am.
Step-by-step explanation:
The distance traveled by the plane after time since it took off is modeled by the equation
And the distance traveled by the jet after time since the plane took off is given modeled by the equation
(we set this up such that at )
Now, the jet will overtake the plane when :
Which is 2 hours and 25 minutes after 6:00 am, or at 8: 25 am; therefore, the jet will overtake the plane at 8:25 am.
Answer:
the answer is 8:25
