Speed of the car = 255 ÷ 4 = 63.75 km/h
Speed of the train = 63.75 + 5 = 68.75 km/h
Answer: 68.75 km/h
Speed of the train = 63.75 + 5 = 68.75 km/h
Answer: 68.75 km/h
[tex]\\ \text{Let the speed of the car is x km/h}\\ \text{Then, the speed of the train is x+5 km/hr}\\ \text{Now, 4 hr is the time of the car}\\ \text{and 7 hour is the time of the train}\\ \text{We know the formula}\\ \text{Distance }= \text{Velocity }\times \text{ time}\\ \text{Distance travelled by car is 4x}\\ \text{Distance travelled by train is }7(x+5)\\ \text{The total distance is given by 255 km. Hence, we have}\\ 4x+7(x+5)=255\\ 4x+7x+35=255\\ 11x=220\\ x=20[/tex]
The speed of the car is 20 km/hr and hence the speed of the train is 2+5=25 km/hr.
The speed of the train is given by 25 km/hr.
