Question

A man is walking at 5km/hr crosses a bridge in 15 min find length of bridge

Answer 1

Distance = Length of Bridge

Speed = 5 km/hr OR 5 × 5/18 m/sec
Speed = 25/18 m/sec

Time = 15 min OR 900 secs

Distance = Speed × Time
= 25/18 × 900
= 25 × 50
= 1250 m

ANSWER = 1250 m OR 1.25 km

Answer 2

Hi there!,

I am solving this with unitary method.

5km/hr

= 5/60
=1/12

Now,
1/12 * 15
= 5/4
= 1 1/4 or 1.25 km.

Hope it helps!!
