Two trains leave stations 324 miles apart at the same time and travel toward each other. one train travels at 95 mph while the other travels at 85 mph how long will it take for the two trains to meet

James performed an experiment to see how adding different salts to water affects their freezing points. his data is shown below. concentration of salt solution (mol solute/kg water) freezing point for nacl solution freezing point for mgcl2 solution 0 0°c 0°c 2 -2.5°c -2.8°c 4 -6.0°c -7.5°c 6 -11.0°c -15.0°c 8 -16.5°c -35.0°c how are the freezing points related to the concentrations of the salt solutions?
