2. A police car drives from a police station to a distance of 170 km in 4 hours. He then stops at a gas station for 1 hour to fill gas and rest. Then the driver goes for 100 Km in 1 hour 30 minutes to his final destination. a. What is the speed of the police car between the police station and the gas station?
b. What is the speed of the police car between the gas station and the final destination?
c. What is the average speed of the police car?

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
