Time Distance and Speed
If I drive with 60 km/hr, I reach 1 hour before and if I drive at 40 km/hr, I reach 30 minutes late. Find the exact time of reaching destination.
A)3½ hours B)4 hours C)2½ hours D)3 hours
Read Solution (Total 2)
-
- X/60-x/40=1-(-30/60)
X/60-x/40=3/2
So..distance is 180
180/60/=y-1...(y is exatact time)
Therefore exact tym is 4hrs - 4 years agoHelpfull: Yes(2) No(2)
- assume total distance=120km
speed=60kkm/hr=>time==2hrs
speed=40km/hr=>time=3hrs
so according to question the condition is satisfied.
if he reaches 30 min or (1/2)hr late at speed of 40km/hr.
let the actual time be=x.
120/40=(x+1/2)
by solving x=5/2 =>2.5hrs. - 4 years agoHelpfull: Yes(1) No(8)
