*Try it risk-free You and your friend decided to take your brand new red sports car out for a spin. A related concept, average velocity, is a vector quantity.*

And we almost have a moral obligation to improve our collective decision-making in terms of climate change and other decisions we need to make at a collective level for humanity."The new research also points to an alternative paradigm for the widespread introduction of artificial intelligence into society, Christakis said.

"Dumb AI" (bots that follow simple rules compared to sophisticated AI) could act as a catalyst rather than a replacement for humans in various kinds of cooperative networks, ranging from the so-called sharing economy (which encompasses services like ride-sharing, home-lending and coworking) to citizen science."We're not trying to build Alpha Go or [IBM's] Watson to replace a person — we are trying to build technology that helps supplement groups of people, and in a way, I think that might be a little less frightening," Christakis said.

The researchers also experimented with putting these bots in different areas of the network.

Sometimes they were placed in central locations that have more connections to other players, and other times they were just placed at random or on the periphery where there are fewer links.

You asked yourself, 'How can a sports car have such a pitiful average speed? It's a scalar quantity which means it is defined only by magnitude.He said it is a very important first step toward a scientific understanding of how similar processes impact human behavior, particularly in the context of interactions between humans and machines."Already we are making our decisions in the context of algorithms and that's only going to expand as technology advances," he told Live Science."We have to be prepared for that and understand these types of processes.Random mutations make evolution possible; random movements by animals in flocks and schools enhances group survival; and computer scientists often introduce noise — a statistical term for random or meaningless information — to improve search algorithms, he said.[Super-Intelligent Machines: 7 Robotic Futures]But the discovery that these effects are mirrored in combined groups of humans and machines could have wide-ranging implications, Christakis told Live Science.For instance, if they give you a rate of feet per second, then your time must be in seconds and your distance must be in feet.Sometimes they try to trick you by using the wrong units, and you have to catch this and convert to the correct units." for both trains?.pass_color_to_child_links a.u-inline.u-margin-left--xs.u-margin-right--sm.u-padding-left--xs.u-padding-right--xs.u-relative.u-absolute.u-absolute--center.u-width--100.u-flex-inline.u-flex-align-self--center.u-flex-justify--between.u-serif-font-main--regular.js-wf-loaded .u-serif-font-main--regular.amp-page .u-serif-font-main--regular.u-border-radius--ellipse.u-hover-bg--black-transparent.web_page .u-hover-bg--black-transparent:hover. Content Header .feed_item_answer_user.js-wf-loaded . "Distance" word problems, often also called "uniform rate" problems, involve something travelling at some fixed and steady ("uniform") pace ("rate" or "speed"), or else moving at some average speed.Whenever you read a problem that involves "how fast", "how far", or "for how long", you should think of the distance equation, Warning: Make sure that the units for time and distance agree with the units for the rate.
