Question
A car travels 80 km. in 2 hours and a train travels 180 km. in 3 hours. The ratio of the speed of the car to that of the train is?Options2 : 33 : 44 : 33 : 2
Solution
To solve this problem, we first need to find the speed of both the car and the train.
Speed is calculated by dividing the distance travelled by the time taken.
-
For the car: Speed = Distance / Time Speed = 80 km / 2 hours = 40 km/hour
-
For the train: Speed = Distance / Time Speed = 180 km / 3 hours = 60 km/hour
Now, we need to find the ratio of the speed of the car to that of the train.
Ratio = Speed of Car : Speed of Train Ratio = 40 : 60
This ratio can be simplified by dividing both numbers by their greatest common divisor, which is 20.
Ratio = 40/20 : 60/20 Ratio = 2 : 3
So, the ratio of the speed of the car to that of the train is 2 : 3.

A goods train and a passenger train are running on parallel tracks in the same direction. The driver of the goods train observes that the passenger train coming from behind overtakes and crosses his train completely in 90 sec, whereas a passenger on the passenger train marks that he crosses the goods train in 40 sec. If the speeds of the trains are in the ratio 1:2, find the ratio of their lengths?
