The question, in short
For v = 3 − 5t, find v at t = 4 and rearrange the formula to express t in terms of v.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Part (a) · 1 mark
Substitute t = 4 into v = 3 − 5t and calculate the resulting value of v.
- 1v = 3 − 5 × 4 = 3 − 20 = −17
Answer−17
Part (b) · 2 marks
Rearrange v = 3 − 5t to make t the subject of the formula.
- 15t = 3 − v
- 2t = (3 − v)/5
Answer(3 − v)/5 or (v − 3)/(−5)
