Q1: A car takes time t = 2.5 +/- 0.2 s to travel a distance d = 0.955 +/- 0.005 m. Find the speed of the car with its absolute uncertainty. PLEASE SOMEONE HELP ME I TRIED TO SOLVE IT BUT EVERY TIME ITS THE SAME ANSWER ​

It would be c hope this out

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
