Мотоцикліст за перші дві години проїхав 60 км, а наступні три години рухався зі швидкістю 54 км/год. Щоб знайти середню швидкість на всьому шляху, потрібно обчислити загальну відстань, яку він проїхав, і поділити її на загальний час подорожі. За перші дві години мотоцикліст проїхав 60 км, а за наступні три години - 54 км/год * 3 год = 162 км. Загальна відстань, яку він проїхав, дорівнює 60 км + 162 км = 222 км. Загальний час подорожі дорівнює 2 год + 3 год = 5 год. Тому середня швидкість на всьому шляху дорівнює 222 км / 5 год = 44,4 км/год. Відповідь: 44,4 км/год.
