In the last question, i.e. Q8, won't we convert 5 hrs to 5/3 since 1hr equals 1/3 in relation as we did for distance i.e. 30/3 = 10 for actual distance? Please clarify. Thanks in advance

Any trick for this Question .A car travels from P to Q at a constant speed. If its speed were increase by 10 km/h, it would have been taken one hour lesser or cover the distance. It would have taken further 45 minutes lesser if the speed was further increased by 10 km/h. The distance between the two cities is
Or we have to solve it by making two linear equation

You have to make two linear equations
and it will be like
10T- S =10 and 20T- 7/4 S = 35
so S=60 kmph and T= 7 hr so D= 420 km
