Multiplier method increase £88 by 14%

if you just want 14% of 88

14% of 88 = 12.32, 0.14 * 88

if you want 14% of 88 + 88

114% of 88 = 100.32, 1.14 * 88

Step-by-step explanation:

2% of x = 0.02 * x

20% of x = 0.2 * x

200% of x = 2 * x

V = 1.94 mi/h

Step-by-step explanation:

You can asume that the current helps her when she is downstream and hinders her when she is upstream.

downstream:

upstream:

If v = x / t, then t = x / v thus the time she took to do each part was:

downstream:

upstream:

The total time is

Therefore:

v≈1,94
