What is the formula of C = a × B in life? For example: distance = speed × time, please write it out, the more the better

Distance = speed × time
Total price = unit price × quantity
Total amount of work = work efficiency × working time
Mass = density × volume
Electric quantity = average current × time
Voltage = resistance × current
Rowing speed + current speed = downstream speed
Rowing speed - current speed = counter current speed
(downstream speed + upstream speed) △ 2 = rowing speed
(downstream velocity countercurrent velocity) △ 2 = flow velocity
Pursuit distance = speed difference × pursuit time
. and a lot more
