Answer 2

Answer:

62.5 ℅

Explanation:

Let's first list all the information that are provided in the question,

Initial speed of the train, u = 80 km/hour

Final speed of the train, v = 130 km/hour

Now let's begin with the solution,

Change in the speed of the train, = v - u = 130 - 80 = 50 km/hour

Now,

Percentage increase in the speed of the train will be calculated as follows-

$\frac{50}{80} \times 100 \\ \\ = \frac{5000}{80} \\ \\ = \frac{500}{8} \\ \\ = 62.5\%$
