A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find:

Using the formula, find:  t for s=30     

 

                                                                 Distance  =  rate • time     

 

                                                                      30 km  =  12 km/hr • t     

 

                                                                                        30 km     

                                                                               t  =  ––––––––     

                                                                                        12 km/hr     

 

                                                                                t  =  2.5 hr
