A train travels 315 km in the same time that a car travels 265 km. If the train travels on average 20 km/h faster than the car,

aev [14]

Answer: 106 km/h,2.5 hr

Step-by-step explanation:

Given

The train travels 315 km in the same time car travels 265 km

The average speed of the train is 20 kmph faster than car

Suppose, speed of the car is v and it travels 265 km in t hours

$\therefore \dfrac{315}{v+20}=\dfrac{265}{v}\\\\\Rightarrow 315v=265\left (v+20\right)\\\\\Rightarrow 315v=265v+5300\\\Rightarrow 50v=5300\\\Rightarrow v=106\ km/h$

Time taken to travel is

$\Rightarrow t=\dfrac{265}{106}}\\\\\Rightarrow t=2.5\ h$
