Question
A part of the Journey is covered in 31.5 minutes at 80 km/h and the remaining part in 16 minutes at 75 km/h. The total distance of the journey is?Options45 km62 km54 km38 km
Solution
To solve this problem, we need to use the formula for distance which is speed multiplied by time.
-
First, we need to convert the time from minutes to hours because the speed is given in km/h. So, 31.5 minutes is 31.5/60 = 0.525 hours and 16 minutes is 16/60 = 0.267 hours.
-
Next, we calculate the distance for each part of the journey. The first part is 80 km/h * 0.525 hours = 42 km. The second part is 75 km/h * 0.267 hours = 20 km.
-
Finally, we add the two distances together to get the total distance. So, 42 km + 20 km = 62 km.
Therefore, the total distance of the journey is 62 km.
