Question

If it has rained 276 mm in the last 3 days, how many cm of rain will fall in one full week (7 days)? Assume that the rain continues to fall at the same rate.

Answer 1

Rain in 3 days = 276 mm
∴ Rain in 1 day = $\frac{276}{3}$
= 92 mm
∴ Rain in 7 days = 92 x 7 = 644 mm
Thus, the rain in 7 days is 644 mm.
