Answer 1

Answer:

please follow me and mark my ans as brianlist

Step-by-step explanation:

Solution :-

Given : A man running at 15 kmph.

Time taken to cross the bridge = 5 minutes.

1 hour = 60 minutes = 15 km

1 minutes = 15/60 = 1/4 km

Formula used :

Distance = Speed × Time

= 1/4 × 5

= 5/4 km

Now,

1 km = 1000 m

5/4 km = (1000 × 5)/4 = 1250 m

Hence,

The length of the bridge = 1250 m.
