Answer 2

Calculation of Time and Distance

a) To calculate the time it takes for the train to travel a distance of 60 km at a speed of 80 km/h, we can use the formula:

Time = Distance / Speed

Substituting the given values:

Time = 60 km / 80 km/h

Simplifying the equation:

Time = 0.75 hours

Therefore, the train will take 0.75 hours (or 45 minutes) to travel a distance of 60 km at a speed of 80 km/h.

b) To calculate the distance the train will travel in 0.3 hours, we can use the formula:

Distance = Speed x Time

Substituting the given values:

Distance = 80 km/h x 0.3 hours

Simplifying the equation:

Distance = 24 km

Therefore, the train will travel a distance of 24 km in 0.3 hours at a speed of 80 km/h.

Please note that the above calculations are based on the given information and assume a constant speed throughout the journey.
