Question: 1

A train is moving with a speed of 92.4 km/hr. How many meters will it cover in 10 minutes.

(A) 15.4

(B) 154

(D) 15400

View Answer

Ans: D

We have, 92.4 km/hr = $$(92.4 × {5} / {18})$$ m/sec

Distance travelled in (10 × 60) sec = $$(92.4 × {5}/{10} × 10 × 60)$$ = 15400 m.

Question: 2

A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?

(A) 3.6

(B) 5.4

(D) 8.4

View Answer

Ans: C

Speed = $$({600} / {5 × 60})$$m/sec = 2 m/sec.

= $$(2 × {18} / {5})$$km/hr = 7.2 km/hr.

Question: 3

A train travels at the speed of 65 km/hr and halts at 8 junctions for a certain time. It covers a distance of 1300 km in 1 day (24 hours). How long does the train stop at each junction, if it halts for the same period of time at all the junctions?

(A) 20 minutes

(B) 30 minutes

(D) 50 minutes

View Answer

Ans: B

Time taken to cover 1300 km = $$({1300} / {65})$$ hrs = 20 hrs.

Halt time = (24 - 20) hrs = 4 hrs.

Halting time at each junction = $$({4 × 60} / {8})$$min = 30 min.

Question: 4

Sound is said to travel in air at about 1100 feet per second. A man hears the axe striking the tree, $${11} / {5}$$ seconds after he sees it strike the tree. How far is the man from the wood chopper?

(A) 2197 ft

(B) 2420 ft

(D) 2629 ft

View Answer

Ans: B

Distance = $$(1100 × {11} / {5})$$feet = 2420 feet.

Question: 5

A person has to cover a distance of 6 km in 45 minutes. If he covers one half of the distance in two thirds of the total time, to cover the remaining distance in the remaining time, his speed (in km/hr) must be

(A) 4

(B) 6

(D) 15

View Answer

Ans: D

Remaining distance = 3 km

Remaining time = $$({1} / {3} × 45)$$min = 15 min = $${1} / {4}$$ hour.
