The body travels 200 m in 4 s. How long will it take it to travel 350 m, moving at the same speed?

Task data: S1 (initial path of the taken body) = 200 m; t1 (first time of movement) = 4 s; S2 (distance that the taken body must travel) = 350 m; the speed of the taken body is constant.

Since the taken body moves at a constant speed, the equality will be true: S1 / t1 = S2 / t2, whence t2 = S2 * t1 / S1.

Let’s perform the calculation: t2 = 350 * 4/200 = 7 s.

Answer: It will take 7 seconds for the body to walk 350 meters.
