Two cars are 15 kms apart. One is turning at a speed of 50kmph and the other at 40kmph . How much time will it take for the two cars to meet?

Read Solution (Total 2)

if they are moving in same direction then solution will be
(50-40)*t=15
ans=1.5hours
if they are moving in opposite direction then ans
(50+40)*t=15
ans=1/6 hours=10min

at 10min or 1/6 hr car A travels 50*(1/6) km
at 10minh or 1/6hr car B travels 40*(1/6) km
so,50*(1/6)+40*(1/6)=15 kms
hence they will meet in 10 min or 1/6 hr
