Can I Do Anything more to make it 100 percent efficient ? (python_3)

Question

def speed():
    q  = input('\nwhat do you want to work out using the speed formula?\n')
    q=q.upper()

Hi
you can still make it more efficient with the libraries offered by python, I recommend them :)

import math
def speed():
    q  = input('\nwhat do you want to work out using the speed formula?\n')
    q=q.upper()
    if q==('SPEED'):
        M = int(input('what is the distance?in (Meters)\n'))
        X = int(input('\nwhat is the time?(mins)\n'))
        S=M/X
        print('the speed is:', S, 'Meters per min')
    if q==('TIME'):
        M1 = int(input('what is the speed?(mpm)#meters per min\n'))
        X1 = int(input('what is the distance?(meters)\n'))
        T=M1/X1
        print('the tme is\n',T,'Minutes')
    if q==('DISTANCE'):
        M2 = int(input('what is the speed?#meters per min\n'))
        X2 = int(input('What is the time?(mins)\n'))
        D=M2/X2
        print('the distance is:\n',D+'Meters')
    else:
        speed()

R = int(input('Enter radius of cylinder:\n'))
H = int(input('Enter height of cylinder:\n'))

V=(math.pi*R*R*H)#EQUATION FOR VOLUME OF CYLINDER
A=(math.pi*2*R*R)+(2*3.14159*R*H)#EQUATION FOR SURFACE AREA OF CYLINDER
print('the volume of the cylinder is :\n',V)
print('the area of the cylinder is:\n',A)
speed()
