The peregrine Falcon is the fastest known bird with a maximum speed of 320 kilometers per hour which of the following equations where D is the distance in kilometer and T is the time in hours represents a speed that is less than the speed of the Falcon choose all correct answers

A) d = 230t

B) d = 3.2t

C) d = 2300t

D) d = 23t

Equations in options A, B, and D gives the speed less than the speed of the Falcon.

Step-by-step explanation:

The peregrine Falcon is the fastest known bird with a maximum speed of 320 kilometers per hour.

Now, in option (A) the distance d, in Km and time t, in hours are related to each other by the equation d = 230t.

Therefore, the speed is 230 km/hour which is less than 320 km/hour.

Now, in option (B) the distance d, in Km and time t, in hours are related to each other by the equation d = 3.2t.

Therefore, the speed is 3.2 km/hour which is less than 320 km/hour.

Now, in option (C) the distance d, in Km and time t, in hours are related to each other by the equation d = 2300t.

Therefore, the speed is 2300 km/hour which is greater than 320 km/hour.

Now, in option (D) the distance d, in Km and time t, in hours are related to each other by the equation d = 23t.

Therefore, the speed is 23 km/hour which is less than 320 km/hour.

Hence, equations in options A, B, and D give the speed less than the speed of the Falcon. (Answer)
