-
Question 87 of 100
A car travels at a constant speed of 55 km/h. How much distance will it cover in 6 hours?
ExplanationDistance = Speed × Time = 55 × 6 = 330 km. Tip: Always ensure units of speed and time match before multiplying.
-
Question 88 of 100
A boat's speed in still water is 26 km/h and the speed of the stream is 8 km/h. Find its downstream speed.
ExplanationDownstream speed = Speed of boat + Speed of stream = 26 + 8 = 34 km/h. Tip: Downstream means with the flow, so speeds add up.
-
Question 89 of 100
Two cars are 278 km apart and moving towards each other at 58 km/h and 47 km/h. In how many hours will they meet?
ExplanationIn opposite directions, Relative Speed = 58 + 47 = 105 km/h. Time = Distance / Rel. Speed = 278 / 105 = 2.65 hours. Tip: Add speeds when objects move towards each other.
-
Question 90 of 100
A boat's speed in still water is 24 km/h and the speed of the stream is 7 km/h. Find its downstream speed.
ExplanationDownstream speed = Speed of boat + Speed of stream = 24 + 7 = 31 km/h. Tip: Downstream means with the flow, so speeds add up.
-
Question 91 of 100
A train 150 meters long is running at a speed of 36 km/h. How many seconds will it take to cross a stationary pole?
ExplanationSpeed in m/s = 36 × (5/18) = 10 m/s. Time = Distance(length of train) / Speed = 150 / 10 = 15 seconds. Tip: For crossing a pole/man, Distance = Length of Train.
-
Question 92 of 100
A train 200 meters long is running at a speed of 54 km/h. How many seconds will it take to cross a stationary pole?
ExplanationSpeed in m/s = 54 × (5/18) = 15 m/s. Time = Distance(length of train) / Speed = 200 / 15 = 13.33 seconds. Tip: For crossing a pole/man, Distance = Length of Train.
-
Question 93 of 100
A boat's speed in still water is 15 km/h and the speed of the stream is 4 km/h. Find its downstream speed.
ExplanationDownstream speed = Speed of boat + Speed of stream = 15 + 4 = 19 km/h. Tip: Downstream means with the flow, so speeds add up.
-
Question 94 of 100
A boat's speed in still water is 20 km/h and the speed of the stream is 2 km/h. Find its downstream speed.
ExplanationDownstream speed = Speed of boat + Speed of stream = 20 + 2 = 22 km/h. Tip: Downstream means with the flow, so speeds add up.
-
Question 95 of 100
Two cars are 217 km apart and moving towards each other at 45 km/h and 32 km/h. In how many hours will they meet?
ExplanationIn opposite directions, Relative Speed = 45 + 32 = 77 km/h. Time = Distance / Rel. Speed = 217 / 77 = 2.82 hours. Tip: Add speeds when objects move towards each other.
-
Question 96 of 100
A car travels at a constant speed of 93 km/h. How much distance will it cover in 5 hours?
ExplanationDistance = Speed × Time = 93 × 5 = 465 km. Tip: Always ensure units of speed and time match before multiplying.
