| To solve this problem, it is necessary to draw up equations for each of the questions. The general equation for finding the distance traveled is V * t = S, where V is speed, t is distance, S is distance. We know the distance – 33 km. Therefore, V * t = 33.
1) To find the speed, you need to transform the original equation.
V * t = S;
V = S / t; where S = 33 km.
V = 33 / t;
2) to find the time that the cyclist moved, we also transform the equation
V * t = S;
t = S / V; where S = 33 km.
t = 22 / V. substitute V.
t = 22 / (33 / t);
t ^ 2 = 22/33.
t = √ (2/3).
3) Substitute t.
V = 33 / √ (2/3).
