Correct Answer: 20 h
Explanation:
We know that, speed = Distance / Time
? Required Time = Distance / Speed = 400/20 = 20 h
Correct Answer: 296 km
Explanation:
We know that, Speed = Distance / Time
? Required distance = Speed x Time
= 37 x 8 = 296 km
Correct Answer: 23 km/h
Explanation:
Required speed = Distance/ Time
= 690/30
= 23 km/h
Correct Answer: 20 km/h
Explanation:
We know that, speed = Distance / Time
? Required speed = 300/15 =20 km/h
Correct Answer: 12 km/h
Explanation:
? 1 m/s = 18/5 km/h
? 31/3 m/s = 10/3 m/s = (10/3) x (18/5) km/h
= 12 km/h
Correct Answer: 16 km/h
Explanation:
We know that for relative speed, the two speeds will be added, if the motions of the two objects are in opposite directions.
? Required speed = 10 + 6 = 16 km/h
Correct Answer: 4 km/h
Explanation:
We know that for relative speed, the subtraction of speeds takes place, if the motions of the two objects are in the same direction.
? Required relative speed = 9 - 5 = 4 km/h
Correct Answer: 24 km
Explanation:
We know that, speed = Distance / Time
Speed = 12/90 km/min
? Distance covered in 3 h = Speed x Time
= (12/90) x (3 x 60) = 24km
Correct Answer: 7 : 2
Explanation:
We know that speed is inversely proportional to time.
Given that, (Speed of A ) : (speed of B ) = 2 : 7
?(Time taken by A ) : (Time taken by B ) = 1/2 : 1/7 = 7 : 2
Correct Answer: 7 km/h
Explanation:
Total distance = 30 + 40 = 70 km
Total time taken = (30/6) + 5 = 10 h
? Required average speed = 70/10 = 7 km/h
