A car can finish a certain journey in 20 hours at a speed of 96 km/hr. In order to cover the
same distance in 16 hours, the speed of the car must be increased to what speed?

posted Jan 19, 2016

D=T1*S1=T2*S2
20*96=16*S2
S2=120KM/HR
speed of car increased to 120kmph

distance = speed * time so distance = 1920
speed = distance / time
speed = 1920/16 = 120km/hr
