Atrain travels at a constant rate of 45 miles per hour.

a. what is the distance, d, in miles, that the train travels in t hours?

b. how many miles will it travel in 2.5 hours?

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

she will travel a distance in the range of 3 - 11 miles
