Explanation

To calculate time, use the formula:

$$text{Time} = frac{text{Distance}}{text{Speed}}$$

Given:

• Distance = 25 km

• Speed = 75 km/h

$$text{Time} = frac{25}{75} = frac{1}{3} text{ hours}$$

Since 1 hour = 60 minutes,

1/3​×60=20 minutes

So, the time taken is 20 minutes.

Explanation

Given:
