Answer:
96.6 minutes
Explanation:
To solve the problem, we can use the formula:
time = distance / speed
where speed is the rate of walking, measured in miles per hour (mph).
First, we need to find the walking speed:
speed = distance / time = 4.8 miles / 4.6 hours ≈ 1.0435 mph
Next, we can use the speed to calculate the time to walk 1.68 miles:
time = distance / speed = 1.68 miles / 1.0435 mph ≈ 1.61 hours
Finally, we can convert hours to minutes:
1.61 hours x 60 minutes/hour ≈ 96.6 minutes
Therefore, it would take about 96.6 minutes (rounded to 1 decimal) to walk 1.68 miles at the given speed.
