Alex runs 3 miles in 60 minutes. To find how far he will run in 4 hours, we can set up a proportion:
3 miles/60 minutes = x miles/240 minutes
We can cross multiply and solve for x:
60x = 3 * 240
60x = 720
x = 720/60
x = 12 miles
Therefore, Alex will run 12 miles in 4 hours if he continues to run at the same rate.
True. If a graph is proportional, it means that the relationship between the variables is directly proportional, which can be represented by a straight line passing through the origin (0,0). To determine if a graph is proportional, you can follow these steps:
1. Identify the equation or relationship being represented by the graph.
2. Check if the equation or relationship can be written in the form y = kx, where k is a constant.
3. If the equation or relationship follows the form y = kx, it is proportional, and the graph should pass through the point (0,0). If it doesn't, then it is not proportional.
