Correct Answer:
Option B —
60 minutes
To find the actual time, we can look at the relationship between speed and time. Since the distance to school remains the same, speed and time are inversely related: if speed decreases, the time taken increases proportionally.Step-by-Step Breakdown
The Change in Speed: Ram is traveling at four-fifths of his original speed.
The Change in Time: Because speed and time are opposites, if the speed is four-fifths of the original, the new time taken will be five-fourths of the original time.
The Difference: The difference between the new time (five-fourths) and the original time (four-fourths) is one-fourth of the original time.
The Delay: The problem states that this one-fourth increase in time is equal to 15 minutes.
Calculating Actual Time: If one-fourth of the actual time is 15 minutes, then the full actual time is 15 multiplied by 4.
Actual Time = 60 minutes
