In a car park, there are 46 vans and motorcycles. If there are 138 wheels altogether, how many motorcycles are there?
Number of vans |
Wheels of vans |
Number of motorcycles |
Wheels of motorcycles |
Total wheels |
46 |
46 x 4 = 184 |
0 |
0 |
184 |
45 |
45 x 4 = 180 |
1 |
1 x 2 = 2 |
182 |
23 |
23 x 4 = 92 |
23 |
23 x 2 = 46 |
138 |
Total number of wheels if all the vehicles are vans
= 46 x 4
= 184
Big difference between the number of wheels between the vans and the motorcycles
= 184 - 138
= 46
Small difference between the number of wheels between a van and a motorcycle
= 4 - 2
= 2
Number of motorcycles
= 46 ÷ 2
= 23
Answer(s): 23
