00:01 Hello we are going to understand this question here it is given that convert 45 km per hour to meter per second given velocity v is equal to 45 kilometer per hour now converting into meter per second 45 we know that in one kilometer there is 1 000 meter so converting kilometer to meter upon in 1 hour there is 60 minute and in one second one minute there is 60 second so in one hour 60 minute and 60 second so converting 60 into 60 now it is converted into meter per second now doing further calculation so here two zero and two zero will get cancelled out from this 45 into 5 upon 18 now doing further calculation so here 45 and 18 both will be divisible by 3 so after doing further simplification into 5 now it is also divisible by 3 so after doing further calculation 5 into 5 upon 2 so after calculation we will get 12 .5 meter per second this is the speed of car in meter per second now in the part a car travels 40 kilometer north in 0 .7 hour.

01:57 So distance traveled by the car distance traveled by car d is equal to 45 kilometer and time is time t is equal to 0 .7 hour.

02:24 So we have to find the average velocity of the car in meter per second.

02:33 So here it is given that car is traveling 45 kilometer in north direction if we are taking x direction x x exercise is north y exercise as a north so displacement vector of the given distance d is equal to 45 j cap average velocity b a v g is equal to total displacement upon total time here displacement is 45 because here in the party we have to find it in kilometer per hour.

03:29 So 45 .7 j -cap kilometer per hour.

03:43 Now doing further calculation so we will get after calculation we will get 64 .3 j -cap kilometer per hour...
