Question
Eliana swam at 3 1/2 miles per hour for 1/4 an hour. How many miles did she travel ( DO NOT include label)?(1 point)
The distance Eliana traveled is calculated by multiplying her speed by the time she swam for.
Distance = Speed x Time
Given that Eliana swam at a speed of 3 1/2 miles per hour for 1/4 an hour, we can substitute the values into the equation:
Distance = 3 1/2 miles per hour x 1/4 hour
To simplify the calculation, we can convert the mixed number 3 1/2 to an improper fraction.
3 1/2 = (7/2)
Substituting the values:
Distance = (7/2) miles per hour x 1/4 hour
To multiply fractions, we multiply the numerators together and the denominators together:
Distance = (7/2) x (1/4)
Multiplying the numerators: 7 x 1 = 7
Multiplying the denominators: 2 x 4 = 8
Distance = 7/8 miles
Therefore, Eliana traveled 7/8 miles.
To find the distance Eliana traveled, we can multiply her speed by the time she swam.
Eliana swam at a speed of 3 1/2 miles per hour, which can also be written as 7/2 miles per hour.
Eliana swam for 1/4 of an hour.
To find the distance, multiply the speed by the time:
Distance = Speed x Time
Distance = (7/2) x (1/4)
To multiply fractions, multiply the numerators and multiply the denominators:
Distance = (7 x 1) / (2 x 4)
Distance = 7/8
Therefore, Eliana traveled 7/8 miles.
To find the distance Eliana traveled, we need to multiply her speed by the time she swam.
Step 1: Convert the mixed number, 3 1/2, to an improper fraction.
3 1/2 = (2 * 3 + 1) / 2 = 7/2
Step 2: Multiply the speed, 7/2 miles per hour, by the time, 1/4 hour.
(7/2) * (1/4) = (7 * 1) / (2 * 4) = 7/8
Therefore, Eliana traveled 7/8 mile.
