**HOTS**

While driving his car at a speed of 50 km/hr, Ramit covers a distance from home to his office in 1 hour 30 minutes. One day he was 15 minutes late from his home. In order to reach office at time, what should be the speed of the car?

Also, find the total distance covered by Ramit daily.

Dear Student,

$Distancecovered=speed\times time=50Km/\overline{)hr}\times 1\frac{1}{2}\overline{)hrs}=50\times \frac{3}{2}Km=75Km\phantom{\rule{0ex}{0ex}}Onedayheis15minutes(\frac{1}{4}hrs)late\phantom{\rule{0ex}{0ex}}So,timehehasleft=(\frac{3}{2}-\frac{1}{4})hrs=\frac{5}{4}hrs\phantom{\rule{0ex}{0ex}}So,speedshouldbe\frac{distance}{time}=\frac{75Km}{{\displaystyle \frac{5}{4}}hrs}=75\times \frac{4}{5}Km/hr=60Km/hr$
