**1.)** Walking at the rate of 4kmph a man cover certain distance in 2hr 45 min. Running at a speed of 16.5 kmph the man will cover the same distance in.

**A. ** 12 min **B. **25 min

**C. **40min ** D. ** 60 min

**View Answer**

**Answer: **Option** C**

**Explanation:**

Distance = Speed * time

4*11/4 = 11km

New Speed = 16.5 kmph

Therefore time = D/S = 11/16.5 = **40min**

**2.)** A train covers a distance in 50 min, if it runs at a speed of 48kmph on an average. The speed at which the train must run to reduce the time of journey to 40min will be.

**A. ** 45 min **B. **60 min

**C. **75 min ** D. ** None of these

**View Answer**

**Answer: **Option** B**

**Explanation:**

Time = 50/60 hr = 5/6hr

Speed = 48mph

distance = S*T = 48 * 5/6 = 40km

time = 40/60hr = 2/3hr

New speed = 40* 3/2 kmph = **60kmph**

**3.)** Two boys starting from the same place walk at a rate of 5kmph and 5.5kmph respectively. What time will they take to be 8.5km apart, if they walk in the same direction?

**A. ** 17 hrs **B. **25 hrs

**C. **31 hrs ** D. ** 45 hrs

**View Answer**

**Answer: **Option** A**

**Explanation:**

The relative speed of the boys = 5.5kmph – 5kmph

= 0.5 kmph

Distance between them is 8.5 km

Time= 8.5km / 0.5 kmph = **17 hrs**

**4.)** Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?

**A.** 4 **B.** 6

**C.** 8 **D.** None of these

**View Answer**

**Answer: **Option **D**

**Explanation:**

Due to stoppages, it covers 9 km less.

Time taken to cover 9 km = (9/54 x 60) min = **10 min.**

**5.)** 2 trains starting at the same time from 2 stations 200km apart and going in opposite direction cross each other at a distance of 110km from one of the stations. What is the ratio of their speeds?

**A.** 7:3 **B.** 11:9

**C.** 18:4 **D.** None of these

**View Answer**

**Answer: **Option **B**

**Explanation:**

In same time, they cover 110km & 90 km respectively

so ratio of their speed =110: 90 =** 11: 9**
