Question

Автомобиль, двигаясь 70км ч , проходит за t часов , расстояние Sкм. Выразить формулой зависимость S от t.

Answer 1

424-1 s = vt, s — 701. В 1 час = 60 минут, значит 30 мин = 0,5 часа. За 3,5 часа автомобиль проехал: s = 701 = 70 • 3,5 = 245 км. За 5 часов автомобиль проехал: s = 70t = 70 • 5 = 350 км. Значит за время от 3 ч 30 мин до 5 ч автомобиль прошёл путь равный: 350 - 245 = 105 км. Ответ: 105 км. 

Answer 2

Formula for Distance Traveled

To express the formula for the distance traveled (S) in terms of time (t) when a car is moving at a speed of 70 km/h, we can use the formula:

S = v * t

Where: - S is the distance traveled in kilometers (km) - v is the velocity or speed of the car in kilometers per hour (km/h) - t is the time taken in hours (h)

In this case, the velocity (v) is given as 70 km/h. Therefore, the formula becomes:

S = 70 * t

This formula allows us to calculate the distance traveled (S) for any given time (t) when the car is moving at a constant speed of 70 km/h.

Please note that this formula assumes a constant speed throughout the entire journey. If the car's speed changes during the journey, the formula will not be accurate.
