Question

Два грузовика едут по шоссе со скоростью 90км/ч расстояние между ними 240 м.Когда грузовик сворачивает на проселочную дорогу,его скорость снижается до 30км/ч.сколько метров будет между грузовекамина проселочной дороге

Answer 1

90 км/ч=1500 м/мин 
30 км/ч=500 м/мин
1) 240/1500=24/150=4/25=0,16 мин - проедет грузовик со скоростью 90 км/ч 240 м
2) 0,16*500=80 м - будет между ними, когда грузовик свернет на проселочную. 

Answer 2

Calculation of the Distance Between Trucks on the Country Road

To calculate the distance between the trucks on the country road, we need to consider the initial distance between the trucks on the highway and the reduction in speed of the turning truck.

Given: - Speed of the trucks on the highway: 90 km/h - Initial distance between the trucks on the highway: 240 m - Speed of the turning truck on the country road: 30 km/h

To calculate the distance between the trucks on the country road, we can use the formula:

Distance = Initial Distance + (Speed of the Turning Truck / Speed of the Trucks on the Highway) × Initial Distance

Let's calculate the distance between the trucks on the country road:

Distance = 240 m + (30 km/h / 90 km/h) × 240 m

Converting the speeds to meters per hour:

Distance = 240 m + (30,000 m/h / 90,000 m/h) × 240 m

Simplifying the calculation:

Distance = 240 m + (1/3) × 240 m

Distance = 240 m + 80 m

Distance = 320 m

Therefore, the distance between the trucks on the country road will be 320 meters.
