В решении.

Пошаговое объяснение:

Формула движения: S=v*t

S - расстояние            v - скорость             t – время

1) v=50км/час       t=3часа 15 минут=3,25 часа.   S=?

S=50 * 3,25 = 162,5 (км).

2)S=180 км       t=2часа 30 минут = 2,5 часа     v=?

v=180 : 2,5 = 72 (км/час).

3)S=100 км       v=60 км/час        t=?

t=100 : 60 = 1 и 2/3 (часа) = 1 час 40 минут.
