Since they are different people with different thoughts and knowledge giving them to choose different numbers all though two of them might choose the same number
Answer:
12.6 km
Step-by-step explanation:
Two people going towards each other meet at the time:
t = d/(v1+v2)
where:
- d is the distance between the people (here, the distance between the villages)
- v1 and v2 are the velocities of each person.
When Ian and Jaden meet:
t1 = d/(42+48) (d is in meters and t is minutes)
When Carter and Jaden meet:
t2 = d/(36+48)
Jaden passed carter 10 minutes after passing Ian, therefore:
t2 - t1 = d/84 - d/90 = 10
6d/7560 = 10
d = 10*7560/6
d = 12600 m = 12.6 km
2 1/4 + 1 1/6 = 3 1/12
5 - 3 1/ 12 = 1 11/12 is how much it grew in the second year.
