I think you can just divide 11 by 4 and you will get the answer to z.
Equation: z = 11/4
z = 2.75
So there’s 32 in total. Is that what you’re asking?
If McKenzie runs 1.5 mp10m, multiply 1.5 by 6. McKenzie runs 9 miles per hour.
Answer:
12/7 hours
Step-by-step explanation:
First find the rate for hour for the two. For Lianne she can do 1/3 of the job per hour. For Julie she can do 1/4 of the job per hour.
Adding them together, 1/3+1/4= 7/12.
This 7/12 means that working together they can finish 7/12 of a job in an hour. We can use the speed*time=distance formula here and see that
7/12 * time = 1 job done
time = 12/7 hours.
