a car moves with a speed of 40 kilometre per hour for 15 minutes and the speed of 60 km per hour for next 15 minutes find the total distance covered by the car in 30 minutes
Answers
Answer:
Explanation ⇒ let speed of 40km per hour for 15min be =v1 ⇒let speed of 60km per hour for 15min be =V2 ⇒THEREFORE distance for V1= speed{V1} *time taken distance for V2= speed{v2}*time taken ⇒distance for v1=40*1000*15/3600 {To convert km into m multiply =1000metres 1000/3600} ⇒distance for v2 = 60*1000*15/3600 =1500metres ⇒total distance in 30 minutes is 1000+2500=2500metres
