Walking at the rate of 4 kmph a man covers certain distance in 2hrs 45 min . Running at a speed of 16.5 kmph the man will cover the same distance in how many minutes ? |

Answer» 35 min. `S_(1) : S_(2)= T_(2) : T_(1)` `4 : 16.5 = T_(2) : 165` or `(4)/(16.5) = (T_(2))/(165)` `T_(2) = (165 XX 4)/(16.5) = 40` min |
