5 m/sec

When we convert 25 m/sec into km/ hour we get 90 km/hour so the difference in their speeds would be
90-72=18 km/hour.. or 5 m/sec (18 km/hour converted in m/sec )jeevan ambati

If the speed of B is converted in Km/hour it would be 80 km/hour... so the difference would be 80-72=8 km/hour or 8 km/hour

sanjeev yadav- Member Since Dec-2007 | Jan 9th, 2008
By Direct approach :
more men,more hectares
moredays,more hectares
so,
8 / 36 : 24 / 30 = 80 / x
x = (36 x 30 x 80) / (8 x 24)
450

B)
let he can select a picnic spot =x m
.
. . x/40+x/30=8
x=137.1 m
so ans is b.rajendraprasad349
- Aug 27th, 2010
Let distance = 'd'
Let us assume forward journey time is 't1'
Return journey time is 't2'
Given t1+t2=8
But time = distance / velocity
t1 = d/40
t2 = d/30
Therefore t1+t2 = d/40 + d/30 = 8
d=137.142

Total time taken by it is following :1.5 (to reach at destination) + 0.5 ( talking halt at station) + 1 (return with 50% speed)so the total time taken by it is 3 hrcurrent time is 8.00 a.m + 3 hr = 11 a.m.So 11 a.m. is the right answer

A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit.
Let ‘x’ be the speed limit. Person ‘A’ was fined for exceeding the speed limit by = 10mphPerson ‘B’ was fined for exceeding the speed limit by = twice of ‘A’ => 2*10mph=20mphgiven that the second person was traveling at the speed of 35mph => 35mph – 20mph = 15mphTherefore the speed limit is =15 mph

ok let us suppose 100 kg of fuel is being wasted.. if i use the A then 30 kg will be saved n 70 kg will be wasted. now if i bring in B it will save 40% of 70 n (70*0.6)=42 kg will be wasted. Now if i incorporate C then it will save 10%of 42 i.e..,(42*0.9) 37.8 kg will be wasted... so 100-37.8=62.2 kg will be saved.. so ans is 62.2%
Anirudh Dayma
- Jul 11th, 2017
Assume total =100 then 30% = 70, 40% reduction = 3/5 and 10% reduction = 9/10. Therefore total reduction = 70X(3/5)X(9/10) = 37.8 therefore ans = 100 - 37.8 = 62.2
