JULIE'S FAMILY TRIP Julie's family is planning a trip to the Grand Canyon, and they are trying to decide whether to drive or to fly. It is approximately 2,000 kilometers directly from their house to the Grand Canyon. Julie and her family will reach their destination in 5 hours if they fly, or in 32 hours if they drive. Both forms of transportation will use the same direct path to the Grand Canyon. When traveling to the grand canyon, how much water is the average speed of the plane than the average speed of the car, in kilometers per hour to the nearest tenth?​

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
