One night the temperature between 1 a. m. and 3 a. m. changed by -0.35°c.
between 3 a. m. and 5 a. m. it changed by -0.5°c and between 5 a. m. and 7 a. m.
it changed by 0.45°c. arlene says that the greatest change in temperature was
between 5 a. m. and 7 a. m. because 0.45 is greater than -0.35 and -0.5.
is arlene correct? explain your reasoning.
