The speed of a train is 60 miles per hour. in 2 hours, the train will cover miles, in 4 hours, the train will cover miles. the train covered more miles in 4 hours than it did in 2 hours.

The train is going 60 miles per hour

In 2 hours

60 * 2 = ?

In 4 hours

60 * 4 = ?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
