Answer:
69 years
Step-by-step explanation:
Sum of Alex's and Ben's current age
= 14 +17
= 31 years
For every year, Alex and Ben will each be one year older. Thus, 2 years would be added to the sum of their ages with each passing year.
Difference in the sum of their ages
= 169 -31
= 138 years
Number of sets of 2 years
= 138 ÷2
= 69
Thus, the sum of their ages will be 169 in 69 years.
Answer:
360 hours
Step-by-step explanation:
To convert 15 days into hours, we need to find hours in a day. There are 24 hours in a day.
We can take 15 days/1 and multiply it by 24 hours/1 day, and we can cancel out the day units.
Then, we multiply 15 by 24 to get 360 hours.
