Aliyah marks a line on her driveway with a piece of chalk and another line 50ft away Then she stands with both feet at the line and runs to the opposite line While she runs she times how long it takes her to get to the other line What is she trying to find with the distance and time

Speed

Explanation:

Aliyah must have been trying to find her speed.

The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,

  speed = with a unit of m/s.

Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed.
