In a flight of 600 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced by 200 km/hr and the time of flight increased by 30 minutes. The duration of the flight is:

A. 1 hour
B. 2 hours
C. 3 hours
D. 4 hours

Explanation:

A man complete a journey in 10 hours. He travels first half of the journey at the rate of 21 km/hr and second half at the rate of 24 km/hr. Find the total journey in km.

A. 220 km
B. 224 km
C. 230 km
D. 234 km

Explanation:

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. 70 km/hr
B. 75 km/hr
C. 84 km/hr
D. 87.5 km/hr

Explanation: Let the speed of two trains be 7x and 8x km/hr.

Then, 8x = 400/4 = 100

x = 100/8 = 12.5

Speed of first train = (7 x 12.5) km/hr = 87.5 km/hr.

A man on tour travels first 160 km at 64 km/hr and the next 160 km at 80 km/hr. The average speed for the first 320 km of the tour is:

A. 35.55 km/hr
B. 36 km/hr
C. 71.11 km/hr
D. 71 km/hr

Explanation: Total time taken = (160/64 + 160/80 hrs. = 9/2 hrs.

Average speed = (320 x 2/9) km/hr = 71.11 km/hr.

A car travelling with 5/7 of its actual speed covers 42 km in 1 hr 40 min 48 sec. Find the actual speed of the car.

A. 17 6/7 km/hr
