If they meet after 8 hours, then the sum of their average speeds is 600/8=75 km per hour. If one is 5 km per hour faster than the other, then if we set the speed of the slower man to x, we have:
2x+5=75
So:
2x=70
x=30
The fastest man is 5 km per hour faster than the slower, so he travels 35 km per hour.
Step-by-step explanation:
Your work is correct, but you need to round. x and y have 2 significant figures, so round your final answer to 2 significant figures:
2.4×10⁶

Step-by-step explanation:
To find out how long will it take for Joe and Bill to finish building the wall together, first find their individual work rates in feet per hour:
Bill:

Joe:

Their combined work rate is:

Then, divide the total size of the wall by their work rate to find the time spent to finish it:
