Answer:
The Multiplication equation to find the number of hours taken to travel the distance is
.
It will taken <u>15 hours</u> by Russian ice breaker to travel a distance of 82.5 km through the ice.
Step-by-step explanation:
Given:
Thickness of the ice = 2.3 m
Speed while moving forward = 5.5 km/h
Distance to travel through the ice = 82.5 km
We need to write and solve the multiplication equation to find the number of hours taken to travel the distance.
Solution:
Let the number of hours taken to travel the distance be 'x'.
Now We know that;
By Distance formula;
Distance traveled is equal to Speed while moving forward multiplied by the number of hours taken to travel the distance.
framing in equation form we get;

Hence The Multiplication equation to find the number of hours taken to travel the distance is 
On Solving above equation we get;
Dividing both side by 5.5 we get;

Hence It will taken <u>15 hours</u> by Russian ice breaker to travel a distance of 82.5 km through the ice.
Answer:
number of miles=a
number of hours=y
Step-by-step explanation:
<h3>$25 per how y of driving</h3><h3>$2 per how many a per mile</h3><h3>a x y = the total price </h3><h3 /><h3 /><h3 /><h3>plz mark me as the brainliest </h3>
The hundred thousand column is the 6th column so you look at the 5th number and round
9 rounds up to 0
but this also changes the 900000 to 1000000
so 992449 = 1000000 to nearest hundred thousand
I think it is D
