janice walks a total of 7/8 hours. she was at the rate of 1 mile every 1/4 hour. how many miles did she walk
To find the number of miles Janice walked, we need to multiply her rate by the time she walked.
Her rate is 1 mile every 1/4 hour, which can be simplified to 4 miles per hour.
The total time Janice walked is 7/8 hours.
Multiplying her rate (4 miles per hour) by the total time (7/8 hours), we get:
(4 miles/hour) * (7/8 hours) = (28/8) miles = 3.5 miles.
Therefore, Janice walked 3.5 miles.
To find out how many miles Janice walked, we can use the formula:
Distance = Rate × Time
Given that Janice walks at a rate of 1 mile every 1/4 hour, and she walks for a total of 7/8 hours, we can calculate the distance as follows:
Rate = 1 mile / (1/4 hour) = 4 miles/hour
Distance = 4 miles/hour × (7/8 hours)
Now let's calculate the distance:
Distance = 4 × (7/8) = 28/8 = 3.5 miles
Therefore, Janice walked a total of 3.5 miles.
3.4 miles is wrong ughhh!!!
and im jus doin this to check my anwers
To find out how many miles Janice walked, we can set up a proportion:
1 mile / (1/4 hour) = x miles / (7/8 hours)
To solve this proportion, we need to cross multiply:
1 * (7/8 hours) = (1/4 hour) * x
Now, we can simplify both sides of the equation:
7/8 hours = 1/4 hour * x
Next, we can divide both sides by 1/4 hour to isolate x:
(7/8 hours) / (1/4 hour) = x
To simplify this division, we can multiply the numerator by the reciprocal of the denominator:
(7/8 hours) * (4/1 hour) = x
Now, we can multiply the numerators and denominators:
(7 * 4) / (8 * 1) = x
28 / 8 = x
Finally, we can simplify the fraction:
x = 3.5
Therefore, Janice walked 3.5 miles.
