You drive a car from Milwaukee to Chicago, which is a distance of 150km and it takes you 95 min. What is its velocity in km/hr and m/s?

94.74 km/hr

26.3 meters/sec

Explanation:

150 km/(95/60) hr = 9000/95 kph  = 94.74 km/hr

(150 km * 1000m/km)/(95 min * 60 sec/min) = 150000/5700 m/sec  

= 26.3 meters/sec

Hopefully, this is right!

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
