Question

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

Answer 1

Rate of rain fall per day = 276/3 =92 mm.

Total amount of rain fall in 7 days = 92×7 =644 mm =64.4 cm.

Answer 2

Measure of rain in 3 days= 276 mm = 27.6 cm

So, measure of rain in 1 day = 27.6 ÷ 3 = 9.2 cm

We know that one week has 7 days.

So, measure of rain in 7 days= 9.2 × 7 = 64.4 cm
