Answer:
125 km
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
