The speed of the train is <u>150 km/hour</u>.
The distance covered by the train in 3 4/5 hours is <u>570 km</u>.
The speed of a body is calculated using the formula, <u>speed = distance/time.</u>
The distance covered is calculated using the formula, <u>distance = speed*time</u>.
The time taken by a body is calculated using the formula, <u>time = distance/speed</u>.
In the question, we are asked for the speed of a train, when it covers a distance of 225 km in 1 1/2 hours.
Distance = 225 km.
Time = 1 1/2 hours = 1.5 hours.
<u>Speed = Distance/Time</u> = 225/1.5 km/hour = 150 km/hour.
Now, we are asked to calculate the distance covered by the train in 3 4/5 hours.
Speed = 150 km/hour.
Time = 3 4/5 hours = 3.8 hours.
<u>Distance = Speed*Time</u> = 150*3.8 km = 570 km.
Thus, the speed of the train is <u>150 km/hour</u>.
The distance covered by the train in 3 4/5 hours is <u>570 km</u>.
The provided question is incorrect. The correct question is:
"A train at a uniform speed covers a distance of 225 km in 1 1/2 hours. Find the speed of the train and the distance covered in 3 4/5 hours.
