A boy is travelling from his home to school at 12 km/hr and reached 7 min late. Next day he traveled at 16 km/hr and reached 8 min early. Distance between home and school?
Answer/Solution
12km
Steps/Work
Let the distance be x
T1 = x/12 hr
T2 = x/16hr
Difference in time = 7+8 = 15 =1/4hr
x/12-x/16 = 1/4
x/48 = 1/4
x = 12 km
Answer is A
T1 = x/12 hr
T2 = x/16hr
Difference in time = 7+8 = 15 =1/4hr
x/12-x/16 = 1/4
x/48 = 1/4
x = 12 km
Answer is A
