If niti drives her car at 5okm/hr from her home,she reaches the office late by 10min. However if she drives at 60km/hr,she reaches the office 5min early.find the distance of the office from her home.

5 + 10 = 15 min = 0.25 hours.
d1 = d2.
50t = 60(t.25)
50t = 60t  15
50t  60t = 15
10t = 15
t = 1.5 h.
D = r*t = 50 * 1.5 = 75 Miles.
