Answer:
14 days
Step-by-step explanation:
Total Problems = 175
Finished Problems = 8
Remaining = 175 - 8 = 167
8 problems in 30 minutes, means:
30/8 = 15/4 = 3.75 minutes per problem
If he works for 45 minutes, at that rate, he can solve:
45/3.75 = 12 problems per day
To finish 167 problems, he will need:
167/12 = 13.91
Rounded, that is <u>14 days more to finish</u>
To determine the number of days, we need to set up equations relating the given values above. The total distance that Kayla would want to travel is a sum of the total distance she traveled from running and the total distance she traveled from biking. So,
200 miles = (6 miles/day) x + (10 miles/day) y
where x is the number of days she spent running and y is the number of days she spent biking.
If the minimum days she used for biking would be 15 days or y = 15, then
200 miles = (6 miles/day) x + (10 miles/day) (15 days)
Solving for x,
200 = 6x + 150
50 = 6x
x = 8.3333 days
Total number of days = 15 days for biking + 8.3333 days for running = 23.3333 days or about 24 days.
32
the greatest common factor of 480 and 128 is 32
480 / 32 = 15
128 / 32 = 4
