If Michael is bike riding at a speed of 4 miles an hour you would multiply 4 miles by the hour

So it would be x times y
0x4=0
1x4=4
2x4=8
3x4=12
4x4=16
5x4=20
9x4=36
1/2x4=2

Miles travelled = 4 x hours

Constant of proportionality: y = 4x

1 hour = 4 miles

2 hours = 8 miles

3 hours = 12 miles. 4 hours = 16 miles. 5 hours = 20 miles. 9 hours = 36 miles.
