A train travels a distance of 120 km at a constant speed of V kmh 1. If the speed is reduced by 10kmh), then the time taken to the journey is increased by one
hour. Find the constant speed V of train.

Help me please

V = 40 km/h

Step-by-step explanation:

Total distance = 120 km

Constant speed of train = V km/h

⇒

Its given that if speed is reduced by 10 km/h , the time taken by train increases by 1 hour. BUT THE DISTANCE REMAINS SAME. So,

Factorise the quadratic equation.

Speed can't be negative. So , V = 40 km/h

if you explain the the question more correctly i might be able to answer this better
