Q:

Karthik could cover a distance of 200 km in 22 days while resting for 2 hrs. per day. In how many days (approx) he will cover a distance of 250 km while resting for 2 hrs. per day and moving with 2/3rd of the previous speed ?

A) 41.25 days
B) 37.5 days
C) 39.75 days
D) 40 days

Answer:   A) 41.25 days 

Explanation:

Given Karthik can cover the distance of 200 kms resting 2 hrs per day in 22 days.
 
Let the initial speed be '1'
 
Hence, Time = 22(24hrs - 2)
 
Now new speed = 2/3
 
Let the number of days he take be 'D'
 
Therefore, 22(24−2)x3/200=D(24−2)x2/250
 
D = 11 x 3 x 5/4 = 41.25 days. = 41 1/4 days.

Karthik could cover a distance of 200 km in 22 days while resting for 2 hrs. per day. In how many days (approx) he will cover a distance of 250 km while resting for 2 hrs. per day and moving with 2/3rd of the previous speed ?

A) 41.25 daysB) 37.5 daysC) 39.75 daysD) 40 days

Answer:   A) 41.25 days 

Explanation:

Given Karthik can cover the distance of 200 kms resting 2 hrs per day in 22 days.

 

Let the initial speed be '1'

 

Hence, Time = 22(24hrs - 2)

 

Noe new speed = 2/3

 

Let the number of days he take be 'D'

 

Therefore, 22(24-2)x3200=D(24-2)x2250

 

D = 11 x 3 x 5/4 = 41.25 days. = 41 1/4 days.
