Question

a car is running at a speed of 60km/hr takes 3 minutes to cross a bridge what is the lenght of the bridge ?​

Answer 1

Answer:

60Km/hr = 6ox 5/18m/sec

Time=3min = I80sec

T =D/speed

Let the length of bridge be x

180 = Xxl8/60x5

x =l80x60x5/18=3ooom

Length of bridge=3ooom

Answer 2

AnswEr :

• Speed = 60 km/hr
• time = 3 minute = $\large\tt{\frac{1}{20}}$ hr

➟ Distance = Speed × Time

➟ Distance = 60 × $\large\tt{\frac{1}{20}}$

➟ Distance = 3 Km

$\therefore$ Distance of Bridge is 3Km.
