In the first 10 minutes, the body covered 900 m. What path will it cover in 0.5 hour, moving at the same speed?

Since the body under consideration, according to the condition, moves at a constant speed, then the path traversed in 0.5 hours is determined from the equality: Sn / tn = V = S / t, whence we express: S = Sn * t / tn.

Variables: Sн – initial path (Sн = 900 m); t is the total time of movement (t = 0.5 h = 30 min); tн – initial time (tн = 10 min).

Calculation: S = Sн * t / tн = 900 * 30/10 = 2700 m = 2.7 km.

Answer: In 0.5 h, the body under consideration covered a distance of 2.7 km.
