Abdullah needs to take a bus to Lahore, which leaves once an hour from his hometown. Nobody in his family knows at exactly how many minutes past the hour the bus is scheduled to depart.Aisha is sure that the number is such that, if it were divided by 3. the remainder would be 2. Sharif is certain that the number is such that, divided by 4, there would be a remainder of 3. Abdullah's father has no doubt that the number of minutes is a multiple of 5.Assuming that they have all given correct information, at how many minutes past the hour does the bus depart?
Correct answer: C. 35
- A. 5
- B. 15
- C. 35
- D. 45
Explanation
The correct answer is 35 minutes past the hour. This number satisfies all the given conditions: When 35 is divided by 3, it leaves a remainder of 2, which matches Aisha's statement. When 35 is divided by 4, it leaves a remainder of 3, which matches Sharif's statement. Finally, 35 is a multiple of 5, which matches Abdullah's father's statement. The other options do not meet all these conditions simultaneously.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.

Al-Jolson Airways runs a scheduled flight from Marseilles to Cairo, stopping at Palermo and Benghazi, every day. The plane takes off from Marseille at 08:00 and arrives at Palermo an hour later.

The aeroplane normally flies at 600 km/h, but on today's flight the pilot encountered turbulence and had to slow down to 500 km/h for 15 minutes. The plane was delayed in the approach to Cairo and had to circle at 300 km/h for 10 minutes before landing. Which of the following graphs best represents the airplane's speed during the journey?
