Answer 2

Answer:

Time spent By Rita on watering plants in 20 days = 13 hours 20 minutes

Step-by-step explanation:

Given:

Time spent on watering plants in 1 day = 40 minutes

Find:

Time spent on watering plants in 20 days = ?

Solution:

Time spent in 1 day = 40 min

Time spent in 20 days = Time spent in 1 day × No. of days

                                      = $40 \times 20$

                                      = $800 \ min$

We know that,

1 hour = 60 minutes

1 minute = ¹/₆₀ hours

∴ 800 minutes = ¹/₆₀ × 800

                         = 13 hours 20 minutes

That is, Rita spends 13 hours and 20 minutes watering plants in 20 days.
