If a car runs at a speed of 60 km/h and takes 180 minutes to cover a certain distance, then what time will it take to cover the same distance at a speed of 40 km?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 4 hr 30 min.
Let's first calculate the distance covered by the car.
We know, Speed = Distance / Time So, Distance = Speed × Time
Given,
Speed = 60 km/h and Time = 180 minutes = 3 hours
Therefore,
Distance = 60 km/h × 3 h = 180 km
Now, we need to find the time taken to cover this distance at a speed of 40 km/h.
Again, using the formula: Time = Distance / Speed
Time = 180 km / 40 km/h = 4.5 hours
So, the car will take 4.5 hours to cover the same distance at a speed of 40 km/h.
