Here's how you solve this problem.
1) find how many kilometers equals 1 mile (16/10=1.6).
2) Divide 100 (from 100 km/h) by 1.6 (1.6×100=62.5).
3) solve for mph.
The answer is 62.5mph.
1/8 of all=mystery
mystery=3
'of' means multiply
therefor
1/8 times all=3
multiply both sides by 8/1 to clear fracion
all=24
