Question

Two planes left the airport traveling in the same direction. the distance plane a traveled is modeled by the function d(t)=290t where d represents distance in miles and t represents time in hours.plane b traveled a total of 540 miles in 2 hours.how does the distance plane a traveled in 1 hour compare to the distance plane b traveled in 1 hour?

Answer 1

The Plan A traveled in 1h is greater than the distance Plane B traveled in 1 h

Explanation:

Answer 2

Plane 1 travels 20 miles farther than plane 2 in an hour.

Explanation:

To compare the distances, compare the speed of each plane. The speed of plane 1 is 290 miles per hour in d(t) = 290t.

Plane 2 travels 540 miles over 2 hours. Its speed is 540/2 = 270 miles per hour.

Plane 1 will travel 20 miles farther than plane 2 in an hour.
