Answer:
4.63
Step-by-step explanation:
we know that
The gear ratio is the ratio between the driver gear and the driven gear
.
if the drive gear (the one directly receiving rotational force from the engine, motor, etc.) is bigger than the driven gear, the latter will turn more quickly, and vice versa.
Higher the gear ratio value, higher will be the speed.
so
Of the 4 gear ratio values given, 4.63 is the highest and hence this gear ratio will have the highest overall speed
therefore
4.63 will have the highest overall speed
