Answer:

1 hour

Explanation:

Given :

Speed = 25 m / sec .

Distance = 90 km .

In term of meter :

Distance = 90000 m.

We know :

speed = distance / time

Time = distance / speed

Time = 90000 / 25 sec

Time = 3600 sec .

Time in term of hours .

Time = 3600 / 60 × 60 hr.

Time = 3600 / 3600 hr.

Time = 1 hr .

Hence time is  1 hour .
