Quantitative Aptitude (CDS) Time & distance

Anshu traveled from the home to school at the rate of 30 kmph and walked back at the rate of 10 kmph. If the whole journey took 4 hours 36minutes, find the distance of the school form the home?

34km

30km

58/3km

69/2km

Explanation:

Average speed = (2xy)/(x+y) kmph
= (2×30×10)/ (30+10)kmph
= 15kmph
Distance travelled in 4 hours 36 minutes i.e, 23/5 hours
= 15×23/5
= 69 km
Distance of the home from the school = 69/2 km
