PLEASE DONT STEAL MY POINTS AND BEST ANSWER GETS BRAINLEST.

A falcon flies 800,000 meters in 4 hours. Use the formula d = rt, where d represents distance, r represents rate, and t represents time, to answer the following questions. Show your work.

Part A: Rearrange the distance formula, d = rt, to solve for rate. (2 points)

Part B: Find the falcon's rate in meters per hour. (3 points)

Part C: Find the falcon's rate in kilometers per hour. (3 points)

Part D: Which unit, meters, or kilometers, makes more sense to use in this scenario, and why? (2 points)

Answer:

see below

Step-by-step explanation:

Part A

d=rt

Divide each side by t

d/t = rt/t

d/t = r

Part B

d =800000 meters and t = 4 hours

800000 meters / 4 hours = rate

200000 meters / hour = rate

Part C

We know that 1000meters = 1 km

200000 meters / hours * 1 km/1000m = 200 km / hour

Part D

We should use km because km is used to measure long distances and 200000 meters is a long distance.

Answer:

Part A : r = d ÷ t

Part B : Rate = 200000 metres per hour

Part C : Rate = 200 kilometres per hour

Part D : Kilometres make more sense to use as the bird can cover long distances in short periods of time.

Step-by-step explanation:

Part A

d = r × t

→ Divide both sides by t

d ÷ t = r ∴ r = d ÷ t

Part B

→ State formula

Rate = Distance ÷ Time

→ Substitute in the values

Rate = 800000 ÷ 4

→ Simplify

Rate = 200000 metres per hour

Part C

→ Convert the distance into kilometres using 1000 m = 1 km

800000 metres = 800 km

→ State formula

Rate = Distance ÷ Time

→ Substitute in the values

Rate = 800 ÷ 4

→ Simplify

Rate = 200 kilometres per hour

Part D

Kilometres make more sense to use as the bird can cover long distances in short periods of time.
