A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?
Part A
Estimate the quotient. Include an equation to show your work. Explain your thinking.
To estimate the quotient, we can round the given distance of 60.9 miles to the nearest whole number, which is 61. To find the estimated distance the cyclist rode in 1 hour, we divide the estimated total distance by the given time of 3.5 hours.
Estimated distance in 1 hour = Estimated total distance / Time
Estimated distance in 1 hour = 61 miles / 3.5 hours
Using long division, we can calculate the estimated quotient:

1.5
The quotient is approximately 17.
Therefore, the cyclist probably rode about 17 miles in 1 hour.
