Question

Скорость автомобиля 75 км/ч а)За какое время он пройдёт 30 км?Б)Какой путь он пройдёт за 0.2ч?

Answer 1

А) t=S:v
t=30км:75км/ч=0,4ч

Б) S=vt
S=75 км/ч * 0,2 ч=15км

Ответ: 0,4 ч; 15 км

Answer 2

Speed and Distance Calculations

To answer your questions about the speed of a car traveling at 75 km/h:

a) To calculate the time it takes for the car to travel 30 km, we can use the formula:

Time = Distance / Speed

Plugging in the values, we have:

Time = 30 km / 75 km/h

Calculating this, we find that the car will take 0.4 hours to travel 30 km.

b) To calculate the distance the car will travel in 0.2 hours, we can use the same formula:

Distance = Speed x Time

Plugging in the values, we have:

Distance = 75 km/h x 0.2 hours

Calculating this, we find that the car will travel 15 km in 0.2 hours.

Please note that these calculations assume a constant speed throughout the journey and do not take into account factors such as acceleration, deceleration, or traffic conditions.
