Ответ:D = (23,7 + 1,8) * 1,5 = 38,025 км.

D = (Vc + Vт) * t,

де D - відстань, Vc - швидкість катера, Vт - швидкість течії, t - час руху.

Підставляємо відомі значення:

D = (23,7 + 1,8) * 1,5 = 38,025 км.

Отже, катер за 1,5 год руху за течією річки подолає відстань 38,025 км.

Пошаговое объяснение:

Щоб знайти відстань, яку подолає катер за 1,5 год руху за течією річки, необхідно використати формулу:

D = (Vc + Vт) * t,

де D - відстань, Vc - швидкість катера, Vт - швидкість течії, t - час руху.

Підставляємо відомі значення:

D = (23,7 + 1,8) * 1,5 = 38,025 км.

Ответ:

s=38,25 км

Пошаговое объяснение:

Vвл.=23,7 км/год

Vт.р.= 1,8 км/год

t=1,5 год

s—? км

(Формули)

V за течією ріки= Vвл.+ Vт.р.

s= V×t

1)23,7+1,8=25,5 (км/год)—V за течією ріки

2)25,5×1,5=38,25 (км)— s

відповідь: 38,25 км
