When an object moves at a constant speed, it can be computed as
Where x is the distance traveled and t the time needed to complete it at the constant speed v
If we wanted to compute t from the equation above, then
Elia rode her bicycle from her house to the beach at 18 km/h and then from the beach to the park at 15 km/h, taking 1 hour in the whole travel, each distance being equal. If we call b as the number of hours it took Elia to ride from her house to the beach, and p the number of hours it took her to ride from the beach to the park, then we can compute
The question doesn't ask for something in particular, so I'm helping you by solving the complete problem. We know the total time is 1 hour, so
Replacing b and p
Multiplying by 90
Simplifying and solving for x
We finally compute b and p
17.27 square centimeters
193.42 square centimeters
386.85 square centimeters
A diameter is a straight line that crosses a circle and the radius equals the half of this distance. So, in our case, the diameter would be YL which equals 12.2 adn the radius would be:
12.2 / 2 = 6.1
Though you could see it this way, there is still another way of finding the radius. The radius is a straght line that goes from the centre to any point of the circle, which is the same thing as saying that it is half of a diameter:
SG is a line going from the centre (S) to G, which is also equal to 6.1
