Answer 3

To find out how many kilometers the cyclist will travel in 4.5 hours, we can use the information given that he traveled 20 km in 1 hour.

To calculate the distance he will travel in 4.5 hours, we can set up a proportion:

Distance in 1 hour / 1 hour = Distance in 4.5 hours / 4.5 hours

Let x be the distance he will travel in 4.5 hours:

20 km / 1 hour = x km / 4.5 hours

Now, we can solve for x:

x = (20 km * 4.5 hours) / 1 hour x = 90 km

So, the cyclist will travel 90 kilometers in 4.5 hours.
