Answer:
Step-by-step explanation:
Given term:
<em>In algebra, like terms are the terms which have the same variables with same powers. </em>
Here the variables are a and d, where d has power 3.
From the given options is the right answers as it has the same variables and power.
Rest of other options are unlike terms to the given term.
Answer:
1. Upstream Time: 1 hour (or 60 minutes)
2. Downstream Time: 0.65 hour (or 39 minutes)
Step-by-step explanation:
The time it will take goes by the distance formula:
, where D is the distance, R is the rate (speed), and T is the time.
For Upstream, you are going <em>against</em> the current, so your still water speed slows down. So upstream rate is still water rate - stream rate. So 2.8 - 0.6 = 2.2mph
Time it will take him to swim 2.2 miles, is:
So, 1 hour
For Downstream, you are going <em>with</em> the current, so your still water speed increases. So downstream rate is still water rate + stream rate. So 2.8 + 0.6 = 3.4 mph
Time it will take him to swim 2.2 miles, is:
So, 0.65 hours (or 0.65*60=39 minutes)
