Answer:
<em>Option C. Luigi runs 150 laps in 10 hours
. </em>
Step-by-step explanation:
<u>Unit Rate</u>
We need to match for an option having a unit rate of 15 laps per hour.
To find the required rate, we divide the number of laps by the number of hours.
A. Luigi runs 44 laps in 4 hour
. This gives a unit ratio of 44/4 = 11 laps/hour. This is not the correct option
B. Luigi runs 2 laps in 30 hours. This gives a unit ratio of 2/30 =0.07 laps/hour. This is not the correct option
C. Luigi runs 150 laps in 10 hours
. This gives a unit ratio of 150/10 = 15 laps/hour. This is the correct option
D. Luigi runs 60 laps in 5 hours. This gives a unit ratio of 60/5 = 12 laps/hour. This is not the correct option
Option C. Luigi runs 150 laps in 10 hours
.
Answer:
240, 360, 800
Step-by-step explanation:
We can call the numbers 3x, 7x, and 10x and then we can write:
3x + 7x + 10x = 1600
20x = 1600
x = 80 so the numbers are 3 * 80 = 240, 7 * 80 = 560 and 10 * 80 = 800.
