long will it take the train to travel
160 miles?

3.56 hours

Step-by-step explanation:

It covers 45 miles in 1 hour.

The train covers 160 miles in 160/45 = 3.56 hours

Speed = Distance/Time

Time = Distance/Speed

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
