One hour = 60 minutes
If it is travelling at 75 kilometers per hour, we can divide 75 by 60 to find out how fast it can travel in one minute.
75/60 = 1.25
The car can travel 1.25 kilometers per minute.
However, the questions is asking how many meters it travels in one minute.
A kilometer is 1000x the size of a meter.
Thus, if we multiply 1.25 by 1000x we'll get the amount of meters.
1.25 * 1000 = 1250
The car travels 1250 meters in one minute.
