If a Newtonian resistance wire has a current of 1.5A flowing through it, the potential difference between the two ends of the wire is 120V. Adjust the voltage to reduce 0.25 times the original voltage, calculate the amperage through the resistance conductor when adjusting the voltage?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
