Verified Answer
A man travelled a distance in 10 hours, the first half at 15 kmph and ...
Time = distance/speed
Let the total distance be x km.
The first half x/2 km was covered with a speed of 15kmph.
The time taken to cover the first half distance = 
The latter half distance was covered with a speed of 5kmph.
Time taken to cover the second half distance = 
Total time taken to cover x km is 10 hours.
⇒ x = 75 km

A man travelled a distance in 10 hours, the first half at 15 kmph and ...
To solve this problem, we can use the formula:
Distance = Speed * Time
Let's assume the total distance traveled is 'd' km.
Given that the man traveled for 10 hours, we can write the equation:
d = (15 kmph) * (t1) + (5 kmph) * (t2)
Since the first half was traveled at a speed of 15 kmph, the time taken (t1) for the first half can be calculated as:
t1 = (1/2) * 10 = 5 hours
Similarly, the time taken (t2) for the second half can be calculated as:
t2 = (1/2) * 10 = 5 hours
Substituting the values of t1 and t2 into the equation, we get:
d = (15 kmph) * (5 hours) + (5 kmph) * (5 hours)
Simplifying the equation, we have:
d = 75 km + 25 km = 100 km
Therefore, the correct answer is option 'd' None of these.
Distance = Speed * Time
Let's assume the total distance traveled is 'd' km.
Given that the man traveled for 10 hours, we can write the equation:
d = (15 kmph) * (t1) + (5 kmph) * (t2)
Since the first half was traveled at a speed of 15 kmph, the time taken (t1) for the first half can be calculated as:
t1 = (1/2) * 10 = 5 hours
Similarly, the time taken (t2) for the second half can be calculated as:
t2 = (1/2) * 10 = 5 hours
Substituting the values of t1 and t2 into the equation, we get:
d = (15 kmph) * (5 hours) + (5 kmph) * (5 hours)
Simplifying the equation, we have:
d = 75 km + 25 km = 100 km
Therefore, the correct answer is option 'd' None of these.
