Distance travelled in 35 min= 54*35/60 =31.5 km
Distance left to be travelled= 100-31.5=68.5 km

Supriya Mondal   9 years AGO

Distance covered in first 35 min=(35/60)*54=31.5 km
So, distance covered in last 25 min=100-31.5=68.5 km
So speed of the man in the last 25 min=(68.5*60)/25=164.4 km/hr
So, option 8)164.4 km/hr is the right answer

susmit   9 years AGO

The distance covered in 35 minutes is 54*35*60 = 31.5 km
Remaining distance is 68.5 km

Devendra Marghade   9 years AGO

Distance covered upto 35 min. @54 Km/hr=54*(35/60)=63/2 Km.
Now distance remained to cover out of total 100 Km=
100-(63/2)=137/2 & time remained=60-35=25 min.
So speed(Km/hr) required=(137/2) / (25/60)=164.4 Km/hr.

speed =distance /time
for the first phase=> find distance covered
dist=54*(35/60) [coz time is given in min so divide by 60 to convert it into hours]
dist=63/2 km
remaining dist= 100-(63/2) km
remaining time=1hr-(25/60) hr
so speed= remaining dist/(remaining time)
=> 168.8 km/hr

Ashish Gahlot   9 years AGO

Given: speed =54 km/hr, time= 35/60 hr;
so, Distance= speed*time= (54*35)/60 =31.5 km

we have to find speed for rest distance i.e. 100-31.5 = 68.5 km.
and time left = 60-35= 25/60 hr

speed for rest distance= (68.5*60)/25 = 164.4 km/hr
