A cyclist moving at a speed of 20 km/hr crosses a bridge in 2 minutes. What is the length of the bridge?

444.4m 555.5m 666.m 777.7m

666.m

Speed = \(\frac{Distance }{Time }\) 20 x \(\frac{5 }{18 }\) = \(\frac{\text{Length of the bridge }}{120 }\) \(\frac{100 }{18 }\) x 120 = Length of the bridge  Length of the bridge = 666.666 m
