A vehicle traveling at a rate of 80 km/hr will cover what distance in 15 minutes?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 20 km
Distance = speed × time, with the time taken in the same unit as the speed, here hours. At 80 km/hr the vehicle covers 80 km in one hour, so in a quarter of an hour it covers a quarter of that.
Time in hours: 15 minutes \(\displaystyle=\frac{15}{60}=\frac{1}{4}\) hour
Distance covered in that time: \(\displaystyle 80\times\frac{1}{4}=20\) km
