Friends…!
We know speed = distance/time
Distance = speed × time
Speed of car given = 65 kilometer/ hour
Time = 1 hour
Hence the distance = 65 km/hour × 1 hour
Distance = 65 kilometer
Now the car speed is reduced by 15 km/hr,
After reduction car speed = 65 kilometer/hour - 15 kilometer/hour
= 50 kilometer / hour
how much time would it take to cover the same distance
Time = Distance / speed
Time = 65 kilometer/ 50 kilometer / hour
Time = 1.3 hours or 1.3 × 60 = 78 minutes
= 60 minutes + 18 minutes
Time = 1 hour 18 minutes
Thus the car will take 1 hour 18 minutes to cover the same distance.
