Use graph paper. Solve. A cyclist took part in a competition. The distance traveled, d meters, after
t minutes, is given by d = 700t. Graph the relationship between t and d.
Use 2 units on the horizontal axis to represent 1 minute and 1 unit on the
vertical axis to represent 350 meters.

a)
What type of graph is it?
b)
What is the distance traveled in 2.5 minutes?
c)
What is the distance traveled in 3.5 minutes?
d)
What is the average speed of the cyclist?
e)
Assuming that the cyclist travels at a constant speed throughout
the competition, what distance will he travel in 7 minutes?
f)
If the cyclist needs to cycle for at least 2.1 kilometers, how many minutes
will he need to cycle? Express your answer in the form of an inequality in
terms of t, where t stands for the number of minutes.
g)
Name the dependent and independent variables.
