Step-by-step explanation:
A.) Eric rode 2 more miles per week than Kim rode
B.)Kim rode 3 more miles per week than Erick rode
C.) Kim rode 11 more miles per week than Erick rode
D.) Eric rode 17 more miles per week than Kim rode
Kim rode her biyciclye 135 miles in 9 weeks.
Number of miles Kim rode per week = Total miles travelled / number of weeks
= 135 miles / 9 weeks
= 15 miles per week
Eric rode her biciclye 102 miles in 6 weeks
Number of miles Eric rode per week = Total miles travelled / number of weeks
= 102 miles / 6 weeks
= 17 miles per week
The correct answer is
A.) Eric rode 2 more miles per week than Kim rode
So it took an hour an 15 minutes which means the distance traveled is their speed+1/4 of their speed, also any answers that have northbound going faster than 6km/h above south is not right so B and D seems to be out of the picture
Answer: 12 hours
Step-by-step explanation:
Given : Working together, it takes Sam, Jenna, and Francisco two hours to paint one room.
When Sam works alone, he can paint one room in 6 hours. When Jenna works alone, she can paint one room in 4 hours.
Let 't' be the time taken by Francisco to paint one room on his own.
Then , we have
Rate of work of Sam +Rate of work of Jenna + Rate of work of Francisco =Rate of work they all do together
i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
i.e. 
i.e. t= 12
Hence, Francisco would take 12 hours to paint one room on his own.
Perimeter= 2 ( length + width)
2×(12+6)
2×18
=36
The answer would be 8.7639
