Answer:</h3>
Distance traveled is 9.055 km
<h3>
Explanation:</h3>
Speed is given by dividing distance by time.
The distance given is 550 ft and the time is 100 seconds.
Therefore; Speed = 550 ft ÷ 100 sec
= 5.5 ft/sec
We can calculate the distance the runner covered in one and half hour.
Time = 1.5 hours
But 1 hour = 3600 sec
1.5 hours = (1.5 × 3600)
= 5400 sec
Distance is given by multiplying speed and time
Thus; Distance = 5.5 ft/sec × 5400 sec
= 29700 ft
But; 1 m = 3.28 ft
1000 m = 1 km
Therefore; 29700 ft will be equivalent to
= 29700 ft/3.28 ft
= 9054.878 M
but 1000 m = 1 km
Thus, distance = 9054.878 ÷ 1000 m
= 9.055 km
