How does the distance Plane A traveled in 1 hour compare to the distance Plane B traveled in 1 hour?

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.

Answer 1

Then plane B has speed of 540/2=270

So plane A is faster because it's speed is 290 per the function
