Janice walks a total of 7/8 hour. She walks at a rate of 1 mile every 1/4 hour. How many miles did she walk

Answer 1

To find the number of miles Janice walked, we need to multiply her walking rate by the total time she walked. Her walking rate is 1 mile every 1/4 hour, so we can find the number of miles by dividing the total time by the rate:
7/8 hour ÷ 1/4 hour = 7/8 ÷ 1/4
To divide by a fraction, we can multiply by the reciprocal:
7/8 ÷ 1/4 = 7/8 * 4/1
Multiplying the numerators and denominators, we get:
7/8 * 4/1 = 28/8
We can simplify 28/8 by dividing the numerator and denominator by their greatest common divisor, 4:
28 ÷ 4 = 7
8 ÷ 4 = 2
So 28/8 simplifies to 7/2, which is equivalent to 3.5. Therefore, Janice walked 3.5 miles. Answer: \boxed{3.5}.
