The distance between 2 cities is 7,200 miles. How long will it take a plane that flies at 600 miles h to travel between the 2 cities?

It would be 12 hours for the plane to go from a city to another/the other city

Step-by-step explanation:

(Distance=speed x time, Speed =distance ÷ time and Time =distance ÷ speed)

If you would apply the formula for time then

7,200m ÷ 600m/h = 12 hours

the answer

b. they are parallel and will never intersect.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
