t = time d = distance

Question

Alana walking rate: 1 meter per second
Gilberto walking rate: 2 meters per second
Leanne walking rate: 2.5 rating per second

Alana Equation: d = t
Gilberto Equation: d = 2t
Leanne Equation: d = 2.5t

I made a table for the first ten seconds of each of the students, and then a graph. What does it mean when it says "If t increases by 1 second, by how much does the distance change? How is this change represented in a change? In a graph?"

What does it mean by "if t increases by 1 second, by how much does the distance change?" How can t increase?

Then it says the same thing, but for 5 seconds, and the question after that says "What is the walking rate per minute? The walking rate per hour?

Answer 1

at 3 m/s,
time t: 3t
time t+1: 3(t+1) = 3t+3
