Final answer:
Fred Flinstone's speed is 90 meters per minute, and it will take approximately 18.89 minutes to walk 1700 meters at that rate.
Step-by-step explanation:
Calculating Walking Time Based on Rate
Fred Flinstone walked 450 meters in 5 minutes. To find out how long it will take to walk 1700 meters, we first calculate his walking speed. The speed is determined by dividing the distance by the time:
Speed = Distance ÷ Time
Speed = 450 meters ÷ 5 minutes = 90 meters per minute
Next, to calculate the time to walk 1700 meters at this speed, we rearrange the speed formula to solve for time:
Time = Distance ÷ Speed
Time = 1700 meters ÷ 90 meters per minute = 18.89 minutes
Thus, it will take Fred approximately 18.89 minutes to walk 1700 meters at the same rate.
