PROBLEM:

CodeMaster is driving his Car on a straight road at the speed of X Kilometers per Hours.The Speedometer of CodeMaster car has turned to be faulty but CodeMaster want to know the speed of his car.

CodeMaster is given two integers D and N.

D:- Distance in kilometers.

N:- Time in hour.

Help the CodeMaster to calculate the speed of the car X and Print the Speed of car.

QUICK EXPLANATION:

We will use the basic formula to calculate the speed of the car. i.e (Speed=Distance/Time).

EXPLANATION:

Here,we are given D(distance) and N(Time in hour) .Formula for finding the speed of the car is Distance/Time(D/N).
Consider D=100km and N=50 hour then speed of the car will be D/N i.e. 100/50= 2 km/hours. so ans will be 2 .
