Question
Amar travelling with 4/9th of his original speed covers 38 km in 100 minutes. Find the actual speed of car.
A) 50.8 kmph
B) 40 kmph
C) 15 kmph
Solution
To solve this problem, we need to first find out Amar's speed when he was travelling at 4/9th of his original speed.
-
We know that speed = distance/time. In this case, the distance is 38 km and the time is 100 minutes. But we need to convert the time to hours because the speed is usually measured in km/h. So, 100 minutes = 100/60 = 1.67 hours.
-
Now we can calculate the speed: speed = 38 km / 1.67 hours = 22.8 km/h. This is Amar's speed when he was travelling at 4/9th of his original speed.
-
To find out his original speed, we need to solve the equation: original speed = 22.8 km/h / (4/9) = 51.3 km/h.
So, the closest answer to the actual speed of the car is A) 50.8 km/h.
