Car moves with speed of 80m/s to go from city a to city b for 12 hours. how long will it take to move car with speed of 60 m/s?

16 hours

Step-by-step explanation:

velocity = distance / time => distance = velocity * time;

distance = 80 m/s * 12 hours

newVelocity = 60 m/s;

newVelocity = distance / newTime => newTime = distance / newVelocity = 80 m/s * 12 hours / (60 m/s) = (8/6) * 12 hours = 16 hours

-7

step-by-step explanation:

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

= (x + 9)^2 - 7.

so q = -7.
