Answer is B. 200 miles
{(y/50)+2} hour=y/30 hour gives y=150 miles. Since, the train already had covered 50 miles at full-speed before the cylinder blew, so the run between the stations was 50+150=200 miles.
Answer:
p(4p - 9) =12 ⇒ 4p² - 9p = 12 ⇒ 4p² - 9p - 12 = 0
- This is a quadratic equation
p(4p - 9) - 12 ⇒ 4p² - 9p - 12
- This is a quadratic expression
