00:05numerical number 3 of unit 1 is an aeroplane travels at 850 km per hour how long does it
00:14take to travel 1 km is an aeroplane which is 850 km per hour so we have to find time
00:30in which
00:32it travels 1 km so we will make data
00:42as speed v is given which is 850 km per hour we have to find time and distance s is
01:02given
01:02which is 1 km so for solution as we know that v is equal to s upon t so we
01:24have to find time
01:25so this equation will be as t is equal to s upon v now by putting the values t will
01:40be
01:40equal to the value of s is 1 divided by v the value of v is 850 so time will
01:49be obtained as
01:490.00117r now we will convert it into seconds in seconds as we know that 1r is equal to 3600
02:14seconds
02:15so time will be obtained as 0.00117r multiplied with 3600 seconds
02:28after multiplying these values we will get the final answer for time is 4.2 seconds so this
02:37is our final answer
