Firstly we need to get the units in same system either cgs or SI
It is better to convert 60 km/h in m/s
For that multiply (60*5)/18 which is equal to 50/3 m/s
For time multiply 45 with 60 which gives us 2700 s
We have a formula which says
speed=distance/time
We calculated the speed and time is given to us
Putting the values in formula
(50/3)=distance/2700
Distance =(50/3)*2700
Which equals 45000m
Dividing it by 1000 we can get 45 km
