Final answer:
Robert will need a minimum of 186 full paces to walk the entire length of a 130-meter bridge since his pace length is 70 centimeters and the bridge length converted to centimeters is 13000 cm.
Step-by-step explanation:
To calculate the minimum number of full paces that Robert would take to walk the full length of the bridge, we first need to convert the length of the bridge from meters to centimeters because the pace length given is in centimeters. Since there are 100 centimeters in a meter, the bridge length is 130 meters × 100 = 13000 centimeters.
Next, we divide the bridge length in centimeters by the length of Robert's pace. Since Robert's pace is 70 centimeters, we would have 13000 cm ÷ 70 cm/pace = approximately 185.7143 paces.
Since Robert can only take full paces, we round up to the nearest whole number, meaning Robert will need to take a minimum of 186 full paces to walk the entire length of the bridge.
