type the correct answer in each box. for a school project, robert records the motion of a snail and plots a position - time graph of the data. from the graph, the distance the snail travels in the first 20 seconds is centimeters. after that, the snail remains in the same place for seconds.

type the correct answer in each box. for a school project, robert records the motion of a snail and plots a position - time graph of the data. from the graph, the distance the snail travels in the first 20 seconds is centimeters. after that, the snail remains in the same place for seconds.

Answer

Answer:

20; 50

Explanation:

Step1: Determine distance in first 20 seconds

At (t = 0) s, (y_1=0) cm. At (t = 20) s, (y_2 = 20) cm. Distance (d=y_2 - y_1=20 - 0=20) cm.

Step2: Determine time of rest

The snail is at rest when position is constant. It starts moving again at (t = 70) s after being at rest from (t = 20) s. So time at rest (=70 - 20=50) s.
