They are separating at the rate of (70/2) = 35 miles per hour, so that's the sum of their speeds.
S + (S+5) = 35
2S + 5 = 35
2S = 30
S = 15
S+5 = 20
Their rates are 15 mph and 20 mph.

2 runners leave the same point running in opposite directions 1 runner runs 2 miles per hour faster than the other After running for 2 hours the runners are 28 miles apart How fast does the faster run?
The equation would be 2x+2(x+2)=28 when x= the speed of the slower runner. If you solve for x you get 6, which is the speed of the slower runner. Then if you add 2 you get the speed of the faster runner-8

The train travelling opposite to the earth spin wear out first because it travel against centrifugal force.
If two bicyclists ride the same coarse on the same bicycle and one bicyclist gets a faster time is it because of the bike rider better or the technology?
If they're using the same bike, then they're using the same technology - so any difference must be found with the rider and not the bike. If both riders are equally sized then there's nothing else than rider differences to blame. If one rider is tall, and the other short, then who the bike fits best can also be an issue.
