Answer:
Common difference is 55
Step-by-step explanation:
C(m)=55m
Substitute m=1 to find the distance traveled by Mia in one hour
55m= 55(1)
= 55
Distance traveled in one hour is 55 miles. Substitute m=2 to find the distance traveled by Mia in 2 hours
55m=55(2)
= 110
Distance traveled in 2 hours is 110 miles. Substitute m=3 to find the distance traveled by Mia in 3 hours
55m=55(3)
= 165
Distance traveled in 3 hours is 165 miles. Substitute m=4 to find the distance traveled by Mia in 4 hours
55m=55(4)
= 220
Distance traveled in 4 hours is 220 miles. Then the common difference is
d=110-55=165-110=220-165=55
The answer is....................................................
1/2 because 2/4 is just half of 4/5
Answer:
Option B
Step-by-step explanation:
Time taken by Nathan to completethe task = 4 hours
Time taken by Elijah to complete the task = 3 hours

Okay so i’m not 100% but i think it’s 37 is the first number then it’s 37/9 x 9/2 which is 18.5 or 18 1/2
but you find it by first doing 4x9 and adding the 1 and then you do keep change flip when dividing fractions and solve it out so i think that’s how you do it :)
