Question
Taimoor left for his school at 6 am by foot and walked at the rate of 2 kmph. After reaching his school he found it was closed and immediately turned back and started walking back to his home at 3 kmph. If he reached his home at 9 am, find the distance between his school and his home.
Answer: Option D
AVERAGE SPEED OF TAIMOOR = (2*2*3)/(2 + 3) = 2.4 KM/HR
IF D IS HE DISTANCE BETWEEN THE SCHOOL AND TAIMOOR’S HOME, THEN TOTAL DISTANCE WALKED BY TAIMOOR = 2D, AND THE TOTAL TIME TAKEN IS 3 HOURS
2.4 = 2D/3
7.2 = 2D
D = 3.6 KM
