Answer» Answer: 12km Step-by-step explanation: LET the DISTANCE of his school from the house be x ⇒ The difference in time =(30−10)min =20min =20/60hr =1/3hr ⇒ Speed during next journey =20+4=24km/hr According to the question, ⇒ x/20−x/24=1/3 ⇒ 10x/120−5x/120=1/3 ⇒ 5x/120=1/3 ⇒ x=(1/3)*(120/5) ⇒ x = 12 ∴ x=12km ∴ The distance of boy school from house is 12km Please mark as BRAINLIEST if the answer is CORRECT

A boy walking at a speed of 20 km/h reaches his school 30 min late. Next time he increspeed by 4 km/h but still he is late by 10 min. Find the distance of the school from hishouse

Answer»

Answer:

12km

Step-by-step explanation:

LET the DISTANCE of his school from the house be x

⇒ The difference in time =(30−10)min

=20min

=20/60hr

=1/3hr

⇒ Speed during next journey =20+4=24km/hr

According to the question,

⇒ x/20−x/24=1/3

⇒ 10x/120−5x/120=1/3

⇒ 5x/120=1/3

⇒ x=(1/3)*(120/5)

⇒ x = 12

∴ x=12km

∴ The distance of boy school from house is 12km

Please mark as BRAINLIEST if the answer is CORRECT
