The body moves up a ten-meter birch tree at a speed of 1 cm / h. Find his driving time.

Initial data: V (the speed with which the body moves up the birch) = 1 cm / h; H (birch height) = 10 m.

1) Let’s translate the body speed from cm / h to m / h (1 m = 100 cm): V = 1 cm / h = 1/100 m / h = 0.01 m / h.

2) Let’s calculate the time of body movement: t = H / V = 10 / 0.01 = 1000 h.

Answer: The time of body movement will be 1000 hours.
