**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. ___**

**Ans-(v) **False
