Question

a train makes 10 hours to complete a certain distance at a speed of 48 km/hr by how much should its speed be increased so that it may take o ly 8 hrs to travel same distance​

Answer 1

Answer:

12 km/hr

Step-by-step explanation:

we know that

v1=d/t

d=v1*t.

d=48*10=480 km

since the distance is same

480/8=v2

v2= 60km/hr

increase in velocity= 60-48

= 12km/hr
