Question

(IV) A train travels a distance of 180 km at a uniforin spccd. If the spccd nad och
8 km/h less, then it would have taken 3 hours more to cover the same distance. We
need to find the speed of the train.​

Answer 1

Answer:60km/h

Step-by-step explanation:

Answer 2

let x be the speed of the train.

180/x-8-180/x=3

180x-180(x-8)=3(x-8)(x)

180x-180x+1440=3x^2-24x

3x^2-24x-1440=0
