Answer:
62390
Step-by-step explanation:
you have to round up if it's 5 or more and round down if it's less.
Let x - hours Carlos drove ; Let y - hours Maria drove
Equation 1: x + y = 4.4
x = 4.4 - y
Equation 2: 55x + 50y = 233
55(4.4 - y) + 50y = 233
242 - 55y + 50y = 233
-5y = 233-242
-5y = -9
y=9/5 or 1.8 hours Maria drove
To find time Carlos drove:
x=4.4 - 1.8
x = 2.6 hours
The rate of this would be 11 sit ups because 55 divided by 5 would give you the answer 11
