Lee walked for 20 minutes on a motorized treadmill that was set at a constant speed of 4 miles per hour. About how many miles did Lee walk on the treadmill?
A. Between 1/2 and 1
B. Between 1 and 1 1/2
C. Between 1 1/2 and 2
D. Between 2 and 2 1/2
E. More than 2 1/2
To calculate the distance Lee walked on the treadmill, we can use the formula:
Distance = Speed x Time
Given that the speed is 4 miles per hour and the time is 20 minutes, we need to convert the time to hours by dividing it by 60.
20 minutes = 20/60 hours = 1/3 hours
Now we can use the formula to calculate the distance:
Distance = 4 miles per hour x 1/3 hours
Distance = 4/3 miles
So, Lee walked about 4/3 miles on the treadmill.
To determine the closest option, let's compare the calculated distance with the given options:
A. Between 1/2 and 1
B. Between 1 and 1 1/2
C. Between 1 1/2 and 2
D. Between 2 and 2 1/2
E. More than 2 1/2
The calculated distance of 4/3 miles falls between 1 and 1 1/2 miles. Therefore, the closest option is B. Between 1 and 1 1/2 miles.
Therefore, the answer is B. Between 1 and 1 1/2 miles.
To find out how many miles Lee walked on the treadmill, we need to calculate the distance covered based on the speed and time. The formula to calculate distance is:
Distance = Speed × Time
In this case, the speed is given as 4 miles per hour and the time is 20 minutes. However, we need to convert the time to hours because the speed is given in miles per hour.
There are 60 minutes in 1 hour, so to convert minutes to hours, we divide the time by 60:
20 minutes ÷ 60 = 1/3 hour
Now we can substitute the values into the formula:
Distance = 4 miles per hour × 1/3 hour
Distance = 4/1 × 1/3
Distance = 4/3 miles
Since the distance is equal to 4/3 miles, which is greater than 1 and less than 1 1/2, we can conclude that Lee walked between 1 and 1 1/2 miles on the treadmill.
Therefore, the answer is B. Between 1 and 1 1/2 miles.
20/60 = 1/3 of an hour
Take it from there.
