# Speed and Time – Quiz 2

### Introduction

Speed and Time is one of important topic in Quantitative Aptitude Section. In Speed and Time – Quiz 2 article candidates can find questions with answers. By solving this questions candidates can improve and maintain, speed, and accuracy in the exams. Speed and Time – Quiz 2 questions are very useful for different exams such as IBPS PO, Clerk, SSC CGL, SBI PO, NIACL Assistant, NICL AO, IBPS SO, RRB, Railways, Civil Services etc.

### Q1

A man walking at the rate of 5 km/hr crosses a bridge in 15 minutes. The length of the bridge (in metres) is
A. 600 B. 750 C. 1000 D. 1250

D
speed = $(\frac{5 \times 5}{18})$m/sec
= $\frac{25}{18}$ m/sec.
Distance covered in 15 minutes = ($\frac{25}{18} \times 15 \times 60$)m
= 1250 m.

### Q2

The number of degrees that the hour hand of a clock moves through between noon and 2.30 in the afternoon of the same day is
A. 720 B. 180 C. 75 D. 65

C
The hour hand moves from pointing to 12 to pointing to half way between 2 and 3. The angle covered between each hour marking on the clock is $\frac{360}{12}$ = 30. Since the hand has covered 2.5 of these divisions the angle moved through is 75.

### Q3

Akash leaves Mumbai at 6 am and reaches Bangalore at 10 am. Prakash leaves Bangalore at 8 am and reaches Mumbai at 11:30 am. At what time do they cross each other?
A. 10 am B. 8 : 32 am C. 8 : 56 am D. 9 : 20 am

C
Time taken by Akash = 4 h
Time taken by Prakash = 3.5 h
For your convenience take the product of times taken by both as a distance.
Then the distance = 14 km
Since, Akash covers half of the distance in 2 hours(i.e at 8 am)
Now, the rest half (i.e 7 km) will be covered by both Prakash and Akash
Time taken by them = $\frac{7}{7.5}$ = 56 min
Thus , they will cross each other at 8 : 56 am.

### Q4

The ratio between the speeds of two trains is 7: 8. If the second train runs 400 kms in 4 hours, then the speed of the first train is ?
A. 83.5 km/hr B. 84.5 km/hr C. 86.5 km/hr D. 87.5 km/hr

D
Let the speeds of two trains be 7X and 8X km/hr.
8x = $\frac{400}{4}$
$\Rightarrow$x= 12.5 km/hr
So speed of first train is 12.5 $\times$ 7 = 87.5 km/hr

### Q5

If Deepesh had walked 20 km/h faster he would have saved 1 hour in the distance of 60km. what is the usual speed of Deepesh?
A. 100 B. 120 C. 150 D. None of these

A
Let the original speed be x km/h, then
$\frac{600}{x}$ - $\frac{600}{(x + 20)}$ = 1
$\Rightarrow 600 \frac{x + 20 -x}{x(x + 20)} = 1$
${x}^{2}$ + 120x - 12000 = 0
$\Rightarrow (x - 120)(x - 100) = 0$
Therefore, original speed = 100 km/h
