Question 106

The distance between two cities is covered in $$3\frac{1}{4}$$ hours at a speed of 52 km/h. If the speed is increased to 65 km/h. how much time would be saved ?

Solution

Distance between two cities is

$$3.25×52=169 KM$$

ao, if he goes by in the speed 65km/h,then time taken$$=169/65=2.6h.$$

So, he will save$$(3.25-2.6)=0.65 h$$

$$=0.65×60minutes=39minutes.$$

A is correct choice.
