Sagot :
400 miles away is the rescue site if the helicopter arrives 1 hour after the plane arrives and the expression 400t = 200(t + 1) represents the time that the plane flies option second is correct.
What is distance?
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
A helicopter is sent from the same base station to rescue wounded persons. If the plane flies 400 mph, the helicopter flies 200 mph, and they leave at the same time.
Let's suppose the plane takes t hours
We know,
Distance = speed×time
400×t = 200(t + 1)
or
400t = 200(t + 1)
After solving we get:
t = 1 hour
Distance = 400×1 = 400 miles
Thus, 400 miles away is the rescue site if the helicopter arrives 1 hour after the plane arrives and the expression 400t = 200(t + 1) represents the time that the plane flies option second is correct.
