A car travels 105 km in 3 hours and a train travels 252 km in 4 hours.

1.	A car travels 105 km in 3 hours and a train travels 252 km in 4 hours. The ratio of speed of the car to that of the train is:1. 9 : 112. 3 : 53. 2 : 74. 5 : 9
Answer» Correct Answer - Option 4 : 5 : 9 Given: Distance traveled by car = 105 km. Time taken by car = 3 hours Distance traveled by train = 252 km. Time taken by train = 4 hours Formula Used: Speed = Distance/Time Calculation: Speed of car = 105/3 = 35 km/h Speed of train = 252/4 = 63 km/h The ratio of the speed of the car to speed of train, \(\frac{{{\rm{Speed\;of\;car}}}}{{{\rm{speed\;of\;train}}}} = \frac{{35}}{{63}} = \frac{5}{9}\) ∴ The ratio of the speed of the car to speed of the train is 5 : 9

A car travels 105 km in 3 hours and a train travels 252 km in 4 hours. The ratio of speed of the car to that of the train is:1. 9 : 112. 3 : 53. 2 : 74. 5 : 9

Answer» Correct Answer - Option 4 : 5 : 9

Given:

Distance traveled by car = 105 km.

Time taken by car = 3 hours

Distance traveled by train = 252 km.

Time taken by train = 4 hours

Formula Used:

Speed = Distance/Time

Calculation:

Speed of car = 105/3 = 35 km/h

Speed of train = 252/4 = 63 km/h

The ratio of the speed of the car to speed of train,

\(\frac{{{\rm{Speed\;of\;car}}}}{{{\rm{speed\;of\;train}}}} = \frac{{35}}{{63}} = \frac{5}{9}\)

∴ The ratio of the speed of the car to speed of the train is 5 : 9
