A man riding on a bicycle at a speed of 66 km/h crosses a bridge in 18 minutes. Find thelength of the bridge?

Correct option is A

Given:

Speed of the man on bicycle = 66 km/h

Time taken to cross the bridge = 18 minutes

Formula Used:

Distance = Speed × Time.

Solution:

18 minutes = $$\frac{18}{60}$$ hours

Now, 

Distance = $$66 \times \frac{18}{60} = 19.8 \, \text{km}$$​​
