Simple Torque Calculation! Answered

Hello! I want to calculate the torque for my project.

I will have 4 individual motors to move a vehicle around 10kg. Here’s the specs:

Wheel weight = 100g Wheel radius = 3” Wheel axis radius = 2” Vehicle weight = 10kg Speed I want to reach = at least 20mph with ease.

Because I’m using four motors, I’m assuming torque needed would also be 1/4 of total torque needed to move the vehicle.

Thank you! I appreciate any help!
