Let’s do the questions from Tutorial 15

Explanation
The correct answer is E.
Speed = Distance / Time = 9 km / 0.75 h = 12 km/h

Explanation
The correct answer is B.
3,927 metres / 11 metres/month = 357 months
357 months / 12 months/year = 29.75 years
i.e. 29 years, 9 months

Explanation
The correct answer is A.
Distance = Speed x Time
but the distance to the post box gets covered in half the time:
(5.5 minutes / 2) x 60 seconds/minute = 165 seconds
2 m/s x 165s = 330 metres

Explanation
The correct answer is C.
112 seconds / 5 questions = 22.4 seconds/question
22.4 seconds / question x 69 questions = 1545.6 seconds
1546 seconds / 60 seconds/minute = 25.76 minutes

Explanation
The correct answer is B.
Speed = Distance / Time = 3 km / (24 / 60 hours) = 7.5 km/h

Explanation
The correct answer is B.
Time = Distance / Speed = 2 x 9.1 cm / 1.3 cm/minute = 14 minutes

Explanation
The correct answer is E.
2 hours x 60 x 60 = 7,200 seconds; 15 minutes x 60 = 900 seconds
Speed = Distance / Time = 42,000 m / 8,125 s = 5.2 m/s (1dp)

Explanation
The correct answer is B.
Remember, the distance to the centre of the labyrinth only represents half his journey. 6 km/h = 0.1 km/min
51 minutes x 0.1 km/min = 5.1 kilometres

Please explain where the 51 minutes comes from, rather than ignoring the comments

Explanation
The correct answer is D.
A = (60 – 0) m/s / 3.5 s = 17.14 m/s2 i.e. 17 m/s2 (2sf)

In the question, it was given that the speed is 60 kmph, how come it can be 60 m/s? It should be converted into m/s by multiplying 60 with 5/18. It will provide 16.66 m/s. now, while dividing with 3.5 sec, answer will be 4.762 m/s s.

I agree this question is wrong, it gives 60km/h not 60m/s

Explanation
The correct answer is C.
Time taken = 41 m/s / 2.6 m/s2 = 16 s (2sf)

Explanation
The correct answer is D.
Change in speed = 6 km/h = 6000m/3600s = 1.66666 m/s
Acceleration = 1.66666 m/s / 18s = 0.0926 m/s2

Where is 10.8 from ?

Explanation
The correct answer is B.
19.8 km/h = 5.5 m/s
5.5 m/s / 3.5s = 1.57 m/s2 = 1.6 m/s2 (1dp)

The table shows times taken by Janet to complete different race stages during a regional triathlon competition.
Explanation
The correct answer is C.
Swim speed = 744 m / 663 s = 1.12 m/s (3sf)
Bike speed = 19,000 m / (36 x 60 + 37 s) = 8.65 m/s (3sf)
8.65 – 1.12 = 7.53 m/s (3sf)

The table shows times taken by Janet to complete different race stages during a regional triathlon competition.
Explanation
The correct answer is C.
Distance = 19,000 + 4,850 + 744 = 24,594 m
Time = (36 + 17 + 11) min (37 + 12 + 3) s = 64 min 52 s
= 3,892 seconds
Average speed = 24,594 m / 3,892 s = 6.32 m/s, hence C
