Two planes left the airport traveling 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 times 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? 

A. The distance plane A traveled in 1 H is less than the distance plane B traveled in 1h 

B. The distance plane A traveled in 1 h is equal to the distance plane B traveled to in 1 H 

C. The distance plane A traveled in 1 h is greater than the distance plane B traveled in 1 H

In one hour Plane A travels  290 (1)  =  290 miles

 

Assuming that Plane B has a constant rate.....it travels   540 / 2 =   270 miles in one hour

 

So.....C is correct
