Let 'd' be the distance among A and B

K -time = d/10 + d/9 = 19d/90 hours

L -time = second/12 = d/6 hours

We recognize that, 10 min = 1/6 hours

Thus, time difference between K and L is given as 10 mins.

=> 19d/90 - d/6 = 1/6

=> (19d-15d)/ninety = 1/6

=> 4d/ninety = 1/6

Thus,

d= 15/four km = 3.75 km.

Consequently the distance among A and B is 3.75 km.

Question forty eight. Joel Travels The First 3 Hours Of His Journey At 60 Mph Speed And The Remaining five Hours At 24 Mph Speed. What Is The Average Speed Of Joel's Travel In Kmph ?

Answer :

Average speed = Total distance / Total time.

Total distance traveled by means of Joel = Distance included inside the first 3 hours + Distance protected in the subsequent 5 hours.

Distance covered within the first 3 hours = 3 x 60 = one hundred eighty miles

Distance covered in the subsequent 5 hours = 5 x 24 = a hundred and twenty miles

Therefore, overall distance traveled = one hundred eighty + a hundred and twenty = three hundred miles.

Total time taken = three + five = 8 hours.

Average speed = 300/eight = 37.5 mph.

We know that 1 mile = 1.6 kms

=> 37.5 miles = 37.5 x 1.6 = 60 kms

Average pace in Kmph = 60 kmph.

Question 53. A Monkey Climbs Up A Greased Pole, Ascends 20m And Slip 4m In Alternate Minutes. If The Pole Is 96m High, How Many Minutes Will It Take To Reach The Top?

Answer :

net peak climbed in 2 min = 20m - 4m = 16m

In 10 min the internet top climbed = sixteen * 10/2 = 80m

Remaining height = 96m - 80m = 16m

In the 11th min , the monkey may be ascending up.

Time taken to ascend the closing 16min

16/20 = four/5min

Total time taken = 10 + 4/five = 54/five min.

Question 54. A Car Is Running At 7/10 Of Its Own Speed Reached A Place In 22 Hours. How Much Time Could Be Saved If The Train Would Run At Its Own Speed ?

Answer :

Since the automobile runs at 7/11 th of its very own velocity, the time it take is eleven/seventh of its common pace.

Allow the usual time taken be t hours

then we are able to write, 11t / 7 = 22

or t = 22 * 7 / 11 = 14 hours

Time stored = 22 - 14 = 8hours.
