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:
x = 6.5
Step-by-step explanation:
You have to apply the distributive property of multiplication:
7(x-2) = 3(x+4)
7x - 14 = 3x + 12
7x - 3x = 12 + 14
4x = 26
x = 6.5
