Question

the passage below describes an experiment. read the passage and think about the variables that are described. peter 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, peter 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, peter 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, peter 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 distance the sled traveled across the flat field the temperature at the hill

Explanation:

In an experiment, the independent variable is the factor that is changed or manipulated to observe its effect on another variable. Here, Peter changes the temperature (it's 16°F in the morning and 33°F in the afternoon) to see how it affects the distance the sled travels. The distance the sled travels is the dependent variable, which depends on the temperature.

Answer:

the temperature at the hill
