Foundation November 2018 Paper 1 Q7
7 A helicopter blade does 3206 full turns in 7 minutes.
Work out the number of full turns per minute. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(3206 \div 7\) | M1 | may be seen as a calculation attempted such as in the ‘bus stop’ method |
| 458 | A1 |
Additional guidance
\(7 \div 3206\) must be recovered eg by correct use in division sum
“Chunking” or build-up must convince that the equivalent to the full division is being attempted (ie reach or go beyond 3206)
Condone \(3206 \div 420\) (working in seconds) for M1
Accept \(\dfrac{3206}{7}\) for M1 unless contradicted by further work
