Question

ПОМОГИТЕ ПОЖАЛУЙСТАААА!!!!!!Из лагеря вышла группа туристов и отправилась к озеру со скоростью 4км/ч . Через 1,5 вслед за ней выехал велосепелист со скоростью 12км/ч. Через какое время и на каком расстоянии от лагеря велосепелист догонит туристов ?

Answer 1

Составим уравнение 4*t=12(t-1,5)

4t=12t-18

8t=18


t=18/8=2 часа 15 минут, 

t -1,5 часа = 45 минут 


12 x 3/4= 9 км 

Answer 2

Calculating the Time and Distance for the Cyclist to Catch Up with the Tourists

To calculate the time and distance for the cyclist to catch up with the tourists, we can use the formula:

time = distance / relative speed

The relative speed is the difference between the speeds of the cyclist and the tourists.

Given: - Speed of the tourists = 4 km/h - Speed of the cyclist = 12 km/h

Calculating the Time

The relative speed of the cyclist catching up to the tourists is: 12 km/h - 4 km/h = 8 km/h

Using the formula: time = distance / relative speed

We can calculate the time it takes for the cyclist to catch up to the tourists.

Time Calculation

time = 1.5 hours (calculated using the formula)

Calculating the Distance

To calculate the distance at which the cyclist catches up to the tourists, we can use the formula: distance = speed × time

Given: - Speed of the cyclist = 12 km/h - Time calculated = 1.5 hours

Distance Calculation

distance = 12 km/h × 1.5 hours = 18 km (calculated using the formula)

Therefore, the cyclist will catch up to the tourists in 1.5 hours and at a distance of 18 km from the camp.

I hope this helps! If you have any other questions, feel free to ask.
