The train 'A' travelled a distance is f 120 km in 3 hours , Whereas another train 'B' travelled a distance of 180 km in 4 hours . Which train tracelled faster

Train B

Explanation:

Let's find each train's speed using the following formula.

where is distance and is time.

Train A

Train A travelled a distance of 120 kilometers in 3 hours.

Substitute the values into the formula and divide.

Train B

Train B travelled a distance of 180 kilometers in 4 hours.

Substitute the values into the formula and divide.

45 kilometers per hour is greater than 40 kilometers per hour, so Train B travelled faster.
