7 Miklos is swimming lengths of a swimming pool.
Each length of the pool is 25 m.
Miklos has swum 178 lengths of the pool.
He wants to swim a total distance of 8050 m.
Calculate how many more lengths Miklos needs to swim. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 144 | P1 | for process to begin to work with length, eg \(8050 \div 25\ (= 322)\) or \(178 \times 25\ (= 4450)\) |
| P1 | for full process to find number of lengths remaining, eg \(\text{``}322\text{''} - 178\) or \((8050 - \text{``}4450\text{''}) \div 25\) or \(3600 \div 25\) | |
| A1 | cao |
Additional guidance
3600 implies the first P1 mark
