00:01 Hi, in this question we have been given the speed is equal to 115 km per hour and in the first part of the question we need to convert this speed in meter per second.
00:14 So here v is equal to 115 km per hour.
00:20 Since we know that 1 km is equal to 1000 meter so we can write this as 111 .15 multiplied by 1 ,000.
00:31 Thousand divided by so one hour is equal to 3600 second so we will write here 3600 and the unit will be now meter per second so we can write here that is since one kilometer is equal to thousand meter and one hour is equal to 3600 second so now if we saw this so this zero and zero will get cancelled up and we will get 115 multiplied by 5 divided by 18 meter per second so on solving this we will get 31 .94 meter per second so we can write speed in meter per second is 31 .94 meter per second is 31 .94 meter per second so this is the final answer for the first part of the question now in the second part of the question we need to convert this speed in miles per hour.
01:40 So again, we will write this v is equal to 115 km per hour...
