I think the answer is 10 seconds, because 50+10=60/2=30. I'm not sure if that's right tho

The best way to look at it is assume there are 60 units of work and the two computers together complete the task in 30 seconds. So together they can do 2 units per second on average. The first computer can do the 60 units of work by itself in 50 seconds, which is 60/50 so it's doing most of the work in the group since the average of the individuals in the group is lower.

If you run a marathon of 26 1/5 miles in a time of 5 4/5 how far do you run in 1 hour<br><br>pls
alisha [4.7K]

First let's make both the miles and the hours ran improper fractions:

26+\frac{1}{5}=\frac{131}{5}\\ 5+\frac{4}{5}=\frac{29}{5}

So, to find our miles per hour, we have to divide the miles by the hours to get: \frac{\frac{131}{5}\text{miles}}{\frac{29}{5}\text{hours}}=\frac{131\text{miles}}{29\text{hours}} \\ \text{ Now we have to divide the top and the bottom by 29 to get our miles per hour so: }\\ \frac{\frac{131}{29}}{\text{hour}} \approx \frac{4.52 \text{miles}}{\text{hour}}
