MULTIPLE CHOICE QUESTIONS EXE-12B
Speed Distance and Time Class 7 ICSE RS Aggarwal Goyal Brothers Foundation Maths Solutions
Choose the correct option in each of the following:
Que-1: Which of the following is correct?
(a) Distance = Speed x Time (b) Time = Distance x Speed (c) Speed = Distance x Time (d) Time = Speed / Distance
Ans- Distance = Speed x Time
so, option (a) is correct
Que-2: To convert a speed of km/hr into m/sec, we multiply it by
(a) 8/15 (b) 18/5 (c) 5/18 (d) 15/8
Ans- To convert speed km/hr into m/sec
multiply it by 5/18
so, option (c) is correct
Que-3: A car is moving with a speed of 90 km/hr. Its speed in m/sec is
(a) 15 m/s (b) 25 m/s (c) 35 m/s (d) 45 m/s
Ans- Speed of car = 90 km/hr
=> 90 x 1000 / 60 x 60 = 25 m/sec
so, option (b) is correct
Que-4: An athlete runs at 30 km/hr. In how much time will he run a race of 200 metres
(a) 20 s (b) 24 s (c) 32 s (d) 36 s
Ans- An athlete runs at speed = 30 km/hr
=> 30 x 5/18 = 150/18
Time taken to run 200 m = Distance / speed
=> 200 x 18 / 150 = 24 sec
so, option (b) is correct
Que-5: A car is moving at a speed of 48 km/hr. How many metres will it travel in 15 minutes?
(a) 8000 m (b) 10000 m (c) 12000 m (d) 16000 m
Ans- Speed of car = 48 km/hr
it will travel in 15 min = 48/60 x 15
=> 12 km = 12000 m
so, option (c) is correct
Que -6: A cyclist covers 175 metres in 25 seconds. What is his speed in km per hour?
(a) 35 km/hr (b) 33.6 km/hr (c) 27 km/hr (d) 25.2 km/hr
Ans- distance covered = 175 m
time taken = 25 s
speed = distance / time
=> 175 / 25 = 7 m/s
=> 7 x 18/5 = 25.2 km/hr
so, option (d) is correct
Que -7: A car covers 108 km in first two hours and 90 km in the next one hour. Its average speed is
(a) 28 km/hr (b) 33 km/hr (c) 66 km/hr (d) 99 km/hr
Ans- A car covers 108 km in first two hours and 90 km in next one hour
3 hour = 108 + 90 = 198 km
speed = distance / time
=> 198 / 3 = 66 km / hr
so, option (c) is correct
MENTAL MATHS
Speed Distance and Time Class 7 ICSE RS Aggarwal Exe-12B MCQs Goyal Brothers Foundation Maths Solutions
Que-1: Fill in the blanks:
(i) A speed of 81 km/hr expressed in metres/sec is ____
Ans-(i) 81 x 5/18 = 22.5 m/s
(ii) Which is greater – a speed of 50 m/sec or 50 km/hr? _____
Ans-(ii) 50 x 5/18 = 13.9 m/s
so, 50 m/s is greater
(iii) If a moving body covers equal distances in equal intervals of time, its speed is said to be ____
Ans-(iii) uniform
(iv) In crossing a platform, a train has to cover a distance equal to the ______ of the lengths of the train and the platform.
Ans-(iv) sum
(v) To convert a speed of m/sec into km/hr, we multiply it by _____
Ans-(v) 18/5
Que-2: Write true (T) or false (F):
(i) A speed of 45 km/hr is the same as 12(1/3) m/s. _____
Ans-(i) False
(ii) Average speed = Total distance covered / Total time taken ______
Ans-(ii) True
(iii) If a moving body covers unequal distances in equal intervals of time, its speed is said to be instantaneous. ______
Ans-(iii) False
(iv) A speed of 1 km/hr is equal to a speed of (5/18) m/s. ____
Ans-(iv) True
(v) A 240 m long train crosses a platform double its length in 54 sec. Then, the speed of the train is 60 km. ___
