Question 1

# How much time does Mr.Surya take to cover a distance of 500 m if he runs at a speed of 25 km/hr?

Solution

Given Speed of surya = 25 km/hr = $$25\times \frac{5}{18} = \frac{125}{18}$$ m/s.

Time taken(T) = Distance Travelled/ Speed

$$\Rightarrow T =\frac{500}{\frac{125}{18}} = 72$$ sec

Hence the time taken by Mr. Surya is '72 sec' or '1.2 min'.
