The speed of a train is 65 km per hour. In 35 minutes and 15 seconds, the train will cover _____ km and ____ metres.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 38; 187.5
Time = 35 minutes 15 seconds = 35 + 15/60 = 35.25 minutes
Time in hours = 35.25 ÷ 60 = 0.5875 hours
Speed of train = 65 km/h
Distance = Speed × Time = 65 × 0.5875 = 38.1875 km
Convert decimal part to metres: 0.1875 × 1000 = 187.5 m
Distance = 38 km, 187.5 m
