Answer 1

Given:

An elephant drinks 49 gallons of water per day.

A rhinoceros drinks 21 gallons of water per day.

To find:

The total amount of water the animals will drink in 8 days.

Solution:

In each day,

Elephant drinks = 49 gallons

Rhinoceros drinks = 21 gallons

Total amount of water they will drink each day is

$49+21=70$

They will drink 70 gallons in each days.

So, total amount of water the animals will drink in 8 days is

$8\times 70=560$

Therefore, they will drink 560 gallons of water in 8 days.
