Answer:
Step-by-step explanation:
Graph shows the proportional relationship between a family's distance from home and the time spent by them in driving.
Distance from home ∝ time
Distance from home = k(time)
Here 'k' = proportionality constant
For a point (1, 49) on the graph,
49 = k(1)
k = 49 miles per hour
And point (1, 49) will represent 49 miles in 1 hour.
Option (3) is the answer.
