One car travels 20 km hr faster than another While one of them travels 240 km the other travels 180 km Find the speed of the fast car?
Difference in distance covered = (240 - 180) = 60 kmBut since speeds differ by 20 kph, difference in distance is (20 x #hours).60 = 20 x #hours#hours = 60/20 = 3 hours.Fast car covers 240 in 3 hours ---> 80 kphSlow car covers 180 in 3 hours ---> 60 kph

While a bicycle travels 4 miles car travels 30 miles how much would the bicycle travel if car travels 40 miles?
If the bicycle travels 4 miles for the car's 30 miles, then if you divide both numbers by 3 you'll see that the bicycle travels 1 and 1/3rd miles for each 10 miles that the car travels. So, if the car travels a further 10 miles (and has now gone 40 miles) the bicycle will travel a further 1 and 1/3rd miles and its total travelled would be 5 and 1/3rd miles.
