smriti kumari  (8 years ago)

for the first 15 km she will stop for 10 min so time taken for 1st 15=15/10+10/60hr=5/3
so in 100 km she will stop 6 times for 15 km an d remaining 10 km is left 100/15
so 6*5/3+10/10=11hrs

sanket burde  (8 years ago)

take breaks after 15 km , to cover 100 km she took breaks for 6 time for 10 min
total break time = 6 * 10 = 60 min = 1 hr
speed = 10 km/hr
time = 100 / 10 = 10
total time taken = time + total break time = 10 + 1 = 11 hrs
she will require 11 hrs to cover 100 km distance

10 hours and 50 min
she covers 100 km with a speed of 10 km/h
so time taken is 10 h
and at each 15 km she will rest for 10 min so 15..30..45..60..75..90 total 5 times she will rest means 50 min

for every 15km ,time taken=time taken for 10km+time taken for 5km+rest time=60+30+10 mins
so 15*6+10km=100*6+60 mins=660mins=11 hours.

for 90 km she take 600 min...
for next 10 km she will take 60 min..
therefore total time taken = 660 min.. which is 11 hours

Saroj kumar  (8 years ago)

Total no of rests=5
Time of rest=50 min
Total no of trip of 15 km=6+ some portion of 7th(I.e 10km)
So total time=1.5*6hr+50 min+1hr=10 hr+50 min...

ride rate is 10 km/h
for 100 km its will take time as 100/15=6.abcd
so it will take rest in hole journey is 6*10=60 and to travel 100 km as per rate 10 km/h its will take 10 hours
