Can someone help the question is in the picture

I choose 100 km/h. This is 27.77778 m/s In order to convert between kilometers per hour and meters per second we must make two conversions. One for kilometers to meters and another for hours to seconds. There are 1000 meters in a kilometer: 100 km/h * 1000m/km = 100000m/h There is one hour in 60 minutes: 100000m/h * (1h/60m) = 1666.667m/min There is one minute in 60 seconds: 1666.667m/min * (1min/60s) = 27.7778 m/s
