the russian ice breaker Yamal can move forward through  2.3 meter 2.3 meter thick ice at a speed  5.5 kilometers 5.5 kilometers per  hour . hour . Write and solve a multiplication equation to find the number of  hours hours it takes to travel  82 kilometers 82 kilometers through ice  Evaluate

Answer 1

Yamal can move the ice to 82 km in approximately 15 hrs.

Explanation:

Given:

Speed = 5.5 km/hr

Distance = 82 km

Let time be represented as 'x'.

We need to find the number of hours required to travel 82 km.

We know that Distance can be calculated by the product of Speed and time.

Framing above sentence in equation form we get;

Distance = Speed × Time

Substituting the given value we get;

`82 = 5.5x`

Hence The expression for number of hours is
`82 = 5.5x`

Solving the equation to find the value of x we get;

`82 = 5.5x\\\\x=(82)/(5.5) = 14.90 \approx 15\ hrs`

Hence Yamal can move the ice to 82 km in approximately 15 hrs.
