The last one: x/2=45; x = 90
the problem says: half of a number is 45.
let's use x to represent this number
we know that dividing by 2 halves a number, so, x/2 = 45
to get x alone, we multiply 2 by 2 to cancel it out. so, multiply by 2 on both sides
x/2 • 2 = 45 • 2
x = 90
hope this helped!

Answer:
We conclude that the train can travel 2240 miles in 16 hours.
Step-by-step explanation:
Given that a super train traveled 420 miles in 3 hours.
- Distance covered = 420 miles
Step 1 of 2
Determine distance per hour
<u>Important Tip:</u>
- The distance per hour can be determined by dividing the distance covered by the time taken.
Distance per hour = Distance Covered / Time taken
= 420 / 3
= 140 miles per hour
Step 2 of 2
Determine the distance traveled in 16 hours
We already know that a super train travels 140 miles per hour. In other words, the speed of the super train is 140 miles per hour.
<u>Important Tip:</u>
- To determine the distance covered in 16 hours, all we need to do is to multiply the distance covered per hour i.e. 140 with the total number of hours i.e. 16.
Distance traveled in 16 hours = Distance per hour × 16
= 140 × 16
= 2240 miles
Conclusion:
Therefore, we conclude that the train can travel 2240 miles in 16 hours.
