= 70 kmph
17. Ravi drives his car at a
speed of 40 kmph and reaches his destination in 5 hours and Ram covers the same
distance in 8 hours. If speed of Ravi is increased by 10 kmph and speed of Ram
is increased by 15 kmph, what would be the difference between the times taken
by them to cover the distance?

a)
1 hour b)2 hours c)45 minutes
d)1.5 hours

**Answer: A**

**Explanation:**Distance covered by Ravi at a speed of 40 kmph in 5 hours

Ã° Distance=
Speed x Time = 40 x 5= 200 km

Ram covers same distance in 8
hours => Speed of Rama =

Distance
Time

=
200
8

= 25 kmph.
Ravi speed is increased by 10 kmph => New
speed of Ravi = 40+10 = 50 kmph

Ram speed is increased by 15 kmph =>New speed of Ram = 25+15 = 40 kmph.

Therefore, time taken by Ravi to cover 200
km at 50 kmph =

200
50

= 4 hours
Time taken by Ram to cover 200
km at 40 kmph =

200
40

= 5 hours
Required time difference = 5 hours – 4 hours
= 1 hour

20. A person rides a motor bike at a speed of 75 kmph and covers his
journey in 6 hours.By how much the speed will to have increase if the same
distance is to be covered in 5 hours ?

a)
15 kmph b)20
kmph c)25 kmph d)28 kmph

**Answer : A**

**Explanation :**Intial speed of motorbike= 75 kmph and time taken to cover the distance=6 hours

Therefore ,
total distance covered = Speed x Time = 75 x 6 =450 km

To cover the same distance of 450 km in 5
hours, speed must be =>

$\frac{Distance}{Time}$ = $\frac{450}{5}$= 90 kmph

Hence,
increase in speed = 90-75 = 15 kmph
