Janice walks a total of 78
hour. She walks at a rate of 1 mile every 14 hour. How many miles did she walk?(1 point)
To find the number of miles Janice walked, we divide the total number of hours she walked by the rate at which she walks.
Total hours walked: 78
Rate of walking: 1 mile per 14 hours
Miles walked = Total hours walked / Rate of walking
= 78 hours / 14 hours/mile
= 5.57 miles
So, Janice walked approximately 5.57 miles.
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?(1 point)
To find the number of miles Janice walked, we divide the total number of hours she walked by the rate at which she walks.
Total hours walked: 7/8 hour
Rate of walking: 1 mile per 1/4 hour
Miles walked = Total hours walked / Rate of walking
= (7/8) hour / (1/4) hour/mile
= (7/8) hour × (4/1) mile/hour
= 28/8 mile
= 3.5 miles
So, Janice walked 3.5 miles.
Wrong
Apologies for the error.
To find the number of miles Janice walked, we divide the total number of hours she walked by the rate at which she walks.
Total hours walked: 7/8 hour
Rate of walking: 1 mile per 1/4 hour
To make the rates compatible, we need to flip the rate of walking:
1 mile per 1/4 hour becomes 4 miles per 1 hour.
Now we can calculate the miles walked:
Miles walked = Total hours walked * Rate of walking
= 7/8 hour * 4 miles/hour
= (7/8) * 4 miles
= 7/2 miles
= 3.5 miles
So, Janice walked 3.5 miles.
