Final answer:
Gwennen's speed is calculated by dividing the distance she rode, which is 2.4 kilometers, by the time it took, which is 8 minutes. The answer is 0.3 kilometers per minute. Therefore correct option is A
Step-by-step explanation:
To calculate Gwennen's speed in kilometers per minute when she rides her bicycle 2.4 kilometers up a steep hill in 8 minutes, you can use the formula for speed, which is distance divided by time. Therefore, the speed is obtained by dividing the total distance traveled by the total time taken.
Speed = Distance ÷ Time
Speed = 2.4 km ÷ 8 min
Speed = 0.3 km/min
So, the answer is (a) 0.3 kilometers per minute.
