a car moving at a speed of 60 km /h covers a certain distance in 4 hours how much time will it take to cover the same distance if its speed is reduced by 20 km/h?
Answers
Answer: time = distance / speed = 240 / 80 = 3 hrs Step-By-Step-Explaination: We know that speed is a physical quantity which is defined as the ratio of distance upon time.
Therefore,
distance = speed x time
distance = 60 x 4 = 240 km
If the speed was 60 + 20 = 80 km/hr
Then the same distance would have been covered in
time = distance / speed = 240 / 80 = 3 hrs
Thus, if the speed were 80kmph, it would have taken only 3 hours to cover the same distance.
