Answer: Length of the bridge is 1.207 km.
Given:
- Speed of man = 2 mph
- Time taken = 1350 sec
To Find: Length of the bridge.
Step-by-step explanation:
Step 1: Distance is the total path length covered by an object. Speed is the rate of distance covered per unit of time.
Speed of man = 2 mph
The speed is given in terms of mph. So we have to convert mph into km/h.
1 mph = 1.60934 km/h
2 mph = 3.21869 km/h
Step 2: Time taken = 1350 sec = 0.375 h
As, we know that the formula for distance in terms of speed and time is,
Distance = Speed x Time
Distance = 3.21869 km/h x 0.375 h
Distance = 3.21869 km/h x 0.375 h
Distance = 1.207 km
The distance covered by the man is the total length of the bridge. So we can say that the total length of the bridge is 1.207 km.
