Question
A car running at a speed of 140 km/hr reached its destination in 2 hours. If the car wants to reach at its destination in 1 hour, at what speed it needs to travel?A)100kmphB)300kmphC)280kmphD)190kmph
Solution
The problem can be solved by using the formula for speed, which is distance divided by time.
Step 1: First, we need to find out the total distance the car traveled. We know the speed of the car is 140 km/hr and it traveled for 2 hours. So, the distance is speed multiplied by time, which is 140 km/hr * 2 hr = 280 km.
Step 2: Now, we want the car to reach the same distance in 1 hour. So, the speed needed would be distance divided by time, which is 280 km / 1 hr = 280 km/hr.
So, the car needs to travel at a speed of 280 km/hr to reach its destination in 1 hour.
Therefore, the correct answer is C) 280 km/hr.
