Ans is E

After 1 hour 40 minutes, the distance D covered is D=5/7*(24-D)
on solving, D = 10km
therefore his speed was distance/time = (10*1000)/(100*60)= 1.66m/s

Let us take the distance traveled till now as d
So, d= 5/7 * (24-d)
which gives d=10 km = 10000 m

1hr40min = 100*60 seconds

s=d/t = 10000/100*60 = 1.66

Ans: E

He covered x and has y to go. We know

x+y= 24 and x=5/7y

so he covered x=10km=10000m in 100min=6000sec

Therefore speed = 10000/6000 = 10/6 = 1,66

Correct answer is E

Let the distance he covered be x. Remaining distance = 24-x
x = 5(24-x)/7
7x = 120 - 5x
x = 10
Time taken to cover 10km = 1hr40 mins = 5/3hr
Speed in km/hr = 10*3/5 = 6
Speed in m/s = 6*5/18 = 5/3 = 1.66

total D =24 => 24 = 5/7x+x
(24 = 5/7x+x) * 7
5x+7x=168
x=14
Therefore he covered 5/7 * 14 = 10 miles in 1hr and 40 min
Speed over this period can be expressed as
10km = 10,000 m
1hr40min= 100 min = 6000 sec
Speed = 10000/6000= 1.66 m/s
