Question

The graph shows the relationship between the distance a bicyclist travels and the time in hours.

Answer 1

Answer:

Step-by-step explanation:

a). Point (x, y) from the graph represents,

    x → Time in hours

    y → Distance traveled by the bicyclist (in miles)

    Therefore, point (4, 60) represents the distance 60 miles traveled by

the bicyclist in 4 hours.

b). Since, distance traveled (d) is proportional to the time taken(t).

    d ∝ t

    d = kt

    k = $\frac{d}{t}$

    Here k = constant of proportionality.

    k = $\frac{60}{4}$ = 15

c). Therefore, equation in the form of y = kx will be,

    y = 15x
