What was his average speed?We know that Average speed = (๐ท๐๐ ๐ก๐๐๐๐ ๐๐๐ฃ๐๐๐๐)/(๐๐๐๐ ๐ก๐๐๐๐) = ๐๐๐/(๐.๐) = 126 ร1/2.5 Removing decimal point =๐๐๐ ร๐/(๐๐/๐๐) =126 ร10/25 =126 ร2/5 =๐๐๐/๐ Now, we do division like we usually do =๐๐๐/๐ Now, we do division like we usually do Thus, ๐๐๐/(๐.๐)=๐๐.๐ So, the average speed at which Ravi travelled was 50.4 km per hour. Note: Answer is 50.4 km/hr not 50.4. Units are important
