Raman drives from his home at the speed of 35 km/h and reaches his college 27 minutes late. The next day he increases his speed by 10 km/h, yet he is late by 15 minutes. How far is his college from his home?
Answer & explanation
Correct answer: option 4
Distance = [\(\frac{S_1 S_2}{S_1 - S_2}\)] × Time Difference
= [\(\frac{35\;×\;45}{10}\)] × \(\frac{27\;-\;15}{60}\)
= 31.5 km
