### Ques 10.

Two boats, traveling at 5 and 10 km per hour, head directly towords each other . They begin at a distance 20 km from each other. How far apart are they (in kms ) one minute before they collide?

#### solutions:

### Ans.1 (c)

### Ans.2

(c) Suppose distance is x km

⇒speed in downstream = ( 3 + 1) km/hr = 4 km/hr⇒speed in upstream = ( 3 + 1) km/hr = 2 km/hr

According to question

⇒ Time-taken by vijay for downstream + time- taken for upstream =

###
** Ans.3**

Required distance =### Ans.4

(d) House 5 km house 7 km stadium

###

Ans.5

(a) Time taken in walking a certain distance from x to y = Time-taken in riding the same distance =

### Ans.6

Let t h be the time taken by the sudhir to reach his bank at the speed of 15 km/hr Then , time taken to reach the bank at the speed of 10 km/hr = (t + 2) h. Now.speed required to reach the bank at 12 noon ( i.e. in 5 h ) = distance / time

Thus, speed =

### Ans.7

Let r = reduction in speed and w = number of wagons

Given that r a /w

r' = 42 - 24 = 18 ; w' = 9

Now let us find out how many wagons will be required so that the train stops . For tht let's take the speed as 0.

For this to happen the reduction has to be 42.

With 49 wagons the train will stop.

Thus we subtract one wagon so that the train will just move.

Hence the answer is 48.

### Ans.8

(b) Let l be length in meters pf the race which A finishes in t seconds.speed of A = speed of B=

speed of C=

Time taken by B to finish the race =

In this time, C covers ( L- 8 ) m,

### Ans.9

=> 10 x = 15 x - 30 or 5 x = 30 or x = 6 hrs and d = 60 km

=> To reach at noon, he cycles for 5 hrs

=> Thus , he cycles at speed =

### Ans.10

**(c)**Relatives velocity of the boats = 15 km/hour =

Therefore, they cover 1/4 km in the last one minute before collision.
