Answer 1

Answer:

(1)30800 meter

Step-by-step explanation:

the formula to find distance is speed × time

and here we know the unit of distance is km/h

the value of speed is 92.4 km per hour

then the time is take by car is 20 minute if we convert minutes into hours then divide with 60

so according to question

92.4×20÷60 then answer will come in km per hour then we multiply with 1000

so the answer is come befor multiply with 1000 that is 30.8km per hour and

after multiply with 1000 that is our final answer that is 30800m/hour

then question must ask in your mind that why we does not divide with 60 it is because according to the question the answer you get in meter per hour thatswhy we shoul not divide with 60 if we divide 60 then answer will come wrong according to your options

so that'swhy my answer is option (1) that is 30800 meter
