Question

Расстояние от турбазы до города велосипедист проехал со скоростью 15 км/ч за 4 ч.Сколько времени он затратит на обратный путь,если будет ехать со скоростью 20 км/ч

Answer 1

1) 15*4=60 км расстояние от турбазы до города
2) 60:20=3 часа на обратный путь

Answer 2

Calculation of Time for the Forward Journey

To calculate the time it took for the cyclist to travel from the tourist base to the city, we can use the formula:

Time = Distance / Speed

Given that the cyclist traveled at a speed of 15 km/h for 4 hours, we can calculate the distance using the formula:

Distance = Speed * Time

Substituting the values, we have:

Distance = 15 km/h * 4 hours = 60 km

Therefore, the distance from the tourist base to the city is 60 km.

Calculation of Time for the Return Journey

To calculate the time it will take for the cyclist to travel back from the city to the tourist base, we can use the same formula:

Time = Distance / Speed

However, this time the cyclist will be traveling at a speed of 20 km/h. We already know that the distance is 60 km. Substituting the values, we have:

Time = 60 km / 20 km/h = 3 hours

Therefore, it will take the cyclist 3 hours to travel back from the city to the tourist base at a speed of 20 km/h.
