A car travels north at 34 ms for 24 min It then travels sout

A car travels north at 34 m/s for 24 min. It then travels south at 43 m/s for 21 min. What is the total distance the car travels?

Solution

distance travelled by car in north direction   Dn = V * t        ; velocity V and time t in seconds

                                                                   = 34 m/s * 24mi * 60 se/mi

                                                                    = 48960 m

simillarly distance travelled by car in south direction Ds = 43m/s * 21 * 60

                                                               = 54180 m

total distance travelled by car = Dn +Ds = 48960 m + 54180 m = 103140 meters
