Question

The Russian ice breaker ,yamal, can move forward through 2.3-meter-thick ice at a speed of 5.5 kilometers per hour. Write and solve a multiplication equation to find the number of hours it will take to travel 82.5 kilometers through the ice

(Remember, I'm in sixth grade , so answer so I can understand it)

Answer 1

Answer: It will take 5 hours.

Answer 2

The train travels at 5.5km per hour.

We know that in x hours it will advance by x*5.5 km.

Hence we need to solve x*5.5=82.5, hence x=82.5/5.5=15

It will take 5 hours
