Answer:
(4) As time increased, distance remained
the same
Explanation:
The graph shows that the student measures equal distance everyday from the bridge to the rock for 7 days.
Everyday has an equal distance measured by the student all through the week.
Let's say the point on the vertical axis which represents distance measured is about 1.5 meters. It means that, for day 1, he measures 1.5 meters, day 2, he measured 1.5 meters, by day 3 another 1.5 meters. Same he does for 7 days. For the first 3 days, he would have measured 1.5 m × 3 = 4.5 meters.
This means that, as time (days) increased, distance measured each day remains the same.
