A train travels a distance of 120 km at a constant speed of V kmh 1. If the speed is reduced by 10kmh), then the time taken to the journey is increased by one
hour. Find the constant speed V of train.

Help me Please

The speed of the train is 40 km/h.

Step-by-step explanation:

Since a train travels a distance of 120 km at a constant speed of V km / h, and if the speed is reduced by 10km / h, then the time taken to the journey is increased by one hour, to find the constant speed V of the train, the following calculations must be performed:

20 x 6 = 120

10 x 7 = 140

30 x 4 = 120

20 x 5 = 100

40 x 3 = 120

30 x 4 = 120

Therefore, the speed of the train is 40 km/h.

the answer is 3,600,000 cubic centimeters

step-by-step explanation:

first you have to convert all the units into centimeters

2 meters = 200 centimeters

1.5 meters = 150 centimeters

to find the volume of a rectangular prism you multiply all the sides

120 * 200 * 150 = 3,600,000

the answer is 3,600,000 cubic centimeters

hope this !
