From place a to place B, it took four hours for passenger cars and three hours for freight cars. Find the speed ratio of passenger cars and freight cars and simplify it
The speed of the bus is 1 / 4
1 / 3 of freight cars
(1/4):(1/3)=3:4
From place a to place B, it takes 8 hours for buses and 10 hours for trucks. What is the speed ratio between buses and trucks______ .
(1 / 8): (1 / 10), = 18:110, = 5:4; answer: the speed ratio of bus and truck is 5:4; so the answer is: 5:4
