Description : The bike and the motorcycle go in the same direction at the same time. The bike runs at an average speed of 20 km / h, the bike runs 3.5 times faster. How long will the distance between the two riders be 30 ... how to deal with it 3.5 times! How do you write it down? :-) Thank you for your help!
Last Answer : I am looking for the time "t", during which: - the bike will travel 20 * t (km) - the motorcycle will travel 3.5 * 20 * t (km), ie 70 * t (km) their distance for the time "t" will be ( 3.5 * 20 * t - 20 * t) and should ... = 30 70 * t - 20 * t = 30 50 * t = 30 t = 30/50 t = 0.6 (h), i.e. 36 minutes
