Answer:
255 steps
Step-by-step explanation:
They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:
140m * 100cm / 1m = 14000
Therefore the bridge would have a length of 14000 centimeters, we divide:
14000/55 = 254.54
Which means that Robert take at least 255 steps to fully walk the bridge.
