A train is traveling at a constant speed and goes 7.5 kilometes in 6 minutes how far does it go in 100 minutes???

125 km

Step-by-step explanation:

We are told the train goes 7.5 kilometres in 6 minutes.

So, distance = 7.5 km and time = 6 minutes.

Now, speed is given by;

Speed = distance/time

Speed = 7.5/6

Speed = 1.25 km/min

Now, to find how far it goes in 100 minutes, we will just plug in speed = 1.25 km/min and time = 100 minutes into the speed equation above.

Thus;

1.25 = distance/100

Distance = 1.25 × 100

Distance = 125 km

1/800 is the right answer

correct answer:

b.(19,-2)
