In a car park, there are 47 lorries and scooters. If there are 100 wheels altogether, how many scooters are there?
Number of lorries |
Wheels of lorries |
Number of scooters |
Wheels of scooters |
Total wheels |
47 |
47 x 4 = 188 |
0 |
0 |
188 |
46 |
46 x 4 = 184 |
1 |
1 x 2 = 2 |
186 |
3 |
3 x 4 = 12 |
44 |
44 x 2 = 88 |
100 |
Total number of wheels if all the vehicles are lorries
= 47 x 4
= 188
Big difference between the number of wheels between the lorries and the scooters
= 188 - 100
= 88
Small difference between the number of wheels between a lorry and a scooter
= 4 - 2
= 2
Number of scooters
= 88 ÷ 2
= 44
Answer(s): 44
