Answer:
Yes,two situation are as follows:
Distance covered by car
(i) Distance=Speed×time
if the speed of the car is increased by 2 units,i.e.(s+2) and time is decreased by 1, i.e.(t- 1),then distance=(s+2)(t -1)
(ii) Simple Interest =PRT/100
=⟩SI=PRT/100
=⟩PRT=SI×100
=⟩P=SI×100/RT
=⟩R=SI×100/PT
=⟩T=SI×100/PR
