Answer:
60 km
Step-by-step explanation:
The closure speed of the trains is 30+30 = 60 km/h. Since their initial distance apart is 60 km, it will take 1 hour for them to collide.

Answer:
(x - 2)
Step-by-step explanation:
Given the quadratic
x² - 7x + 10
To factor consider the factors of the constant term ( + 10) which sum to give the coefficient of the x- term ( - 7)
The factors are - 5 and - 2 since
- 5 × - 2 = + 10 and - 5 + (- 2) = - 7, thus
x² - 7x + 10 = (x - 5)(x - 2)
