A train travels 92.5 km/hr. How many meters will it travel in 18 minutes?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 27750
Distance = speed × time, with the time in the same unit as the speed (hours), and the answer then changed from kilometres to metres. A speed of 92.5 km/hr means 92.5 km in every hour, so in a fraction of an hour the train covers that fraction of 92.5 km.
Time in hours: 18 minutes \(\displaystyle =\frac{18}{60}=0.3\) h
Distance in kilometres: \(92.5\times0.3=27.75\) km
In metres (1 km = 1000 m): \(27.75\times1000=27750\) m
