Question

josiah heard that when it was cold outside, a sled would travel farther after it got to the bottom of a hill. to test this idea, josiah headed to the sledding hill near his house on a cold winter morning. when he got to the hill, the temperature outside was 16°f. starting from the top of the hill, josiah rode straight down the hill three times. for each ride, he measured the distance he traveled across the flat field at the bottom of the hill. then, josiah waited until mid - afternoon, when the temperature outside had increased to 33°f. he rode straight down the hill three more times and measured how far he traveled across the field. which of the following was an independent variable in this experiment? the temperature at the hill the distance the sled traveled across the flat field

Explanation:

An independent variable is what is changed in an experiment. Josiah changed the temperature (16°F in the morning and 33°F in the afternoon) to see its effect on the sled - travel distance. The distance the sled traveled is the dependent variable as it depends on the temperature.

Answer:

the temperature at the hill
