A car travels a distance of 15 km at a speed of 80 kmph. Tell how long it will cover the distance at a speed of 60 km per hour.
Explanation
Time = Distance / Speed
Time = 15 km / 80 kmph = 0.1875 hours
Multiply by 60 to convert to minutes:
0.1875 x 60 = 11.25 minutes
Now, find the time at 60 kmph:
Time = 15 km / 60 kmph = 0.25 hours
Multiply by 60 to convert to minutes:
0.25 x 60 = 15 minutes
Answer: 15 minutes
