Step-by-step explanation:
The speed is 630mp/s I think. Because you have to multiply Wavelength by Frequency to get true speed
Walk = x + 6
Bike = x
Driven = x
x + x + x + 6 = 24
combine like terms
3x + 6 = 24
subtract 6 from both sides
3x = 18
divide both sides by 3 to isolate x
x = 6
Walk = x + 6 = 6 + 6 = 12
