Answer 2

HOLA MATE !!!

HOPE THIS HELPS YOU ...

Answer:

Given data,

CASE 1:-

Velocity of train ,v = d/t

Distance travelled by the train , d = 90km

Time taken to travel 90km ,t = 1.5 hours

CASE 2:-

Velocity of the train, v = 60kmph

Time taken to travel with speed 60kmph ,t =3.5hours

Total distance travelled , d =vt

Step-by-step explanation:

For CASE 1 :-

Velocity of train ,v = d/t = 90/1.5 =60kmph

Hence,velocity of train travelling 90kms in 1.5hours =60kmph

For CASE 2:-

Total distance travelled ,d = vt = 60 * 3.5 =210kms

Hence ,total distance travelled with velocity 60kmph in 3.5 hours =210kms
