Question

Автомобиль движется со скоростью 80км/ч сколько он преодолеет за 120мин.,30мин,за 15мин, сможет ли он преодолеть 20м.за1с

Answer 1

80*2=160 км(за 120 мин.)
80/2=40 км(за 30 мин.)
80/4=20 км(за 15 мин.)

Answer 2

Умножь и все.
S=vt
80•120=9600
80•30=2400
80•15=960

Answer 3

Calculation of Distance Covered by a Car

To calculate the distance covered by a car, we can use the formula:

Distance = Speed × Time

Let's calculate the distance covered by the car in different time intervals:

1. For 120 minutes (2 hours): - Speed: 80 km/h - Time: 120 minutes = 2 hours - Distance = 80 km/h × 2 hours = 160 km

2. For 30 minutes: - Speed: 80 km/h - Time: 30 minutes = 0.5 hours - Distance = 80 km/h × 0.5 hours = 40 km

3. For 15 minutes: - Speed: 80 km/h - Time: 15 minutes = 0.25 hours - Distance = 80 km/h × 0.25 hours = 20 km

4. For 1 second: - Speed: 80 km/h - Time: 1 second = 0.00027778 hours (approximately) - Distance = 80 km/h × 0.00027778 hours = 0.022222 km (approximately)

Therefore, the car will cover: - 160 km in 120 minutes, - 40 km in 30 minutes, - 20 km in 15 minutes, - and approximately 0.022222 km in 1 second.

Please note that the calculation for 1 second is an approximation, as it is unlikely that a car can maintain a constant speed of 80 km/h for such a short duration.
