Answer:
Step-by-step explanation:
What you are trying to do is a nice way to solve this problem. Without knowing any physics, you are using what math you know to get the answer. You are actually very close to being correct, and you are right. You do have to divide by 60.
Here's why and it is the one bit of physics you have to know.
The speed is km/hour. That word hour is the culprit. Your time is in minutes and you have to get it into hours. In physics, the units have to be consistent.
So ...
b1 = 19 minutes which is 19 min [1 hour / 60 minutes] = 19/60 = 0.31667 hour
b2 = 26 minutes which is 26 min [ 1 hour/60 minutes] = 26/60 = 0.4333 hour
h = 40 km/hour
Area = (0.31667 hour + 0.4333 hour)*40 km/hour /2
Area = 0.75 hour * 40 km/hr //2
Area = 15 km
<span>Let's say you divide 25 by 4. You will get a quotient 6, but have that remainder of 1. You could also divide 37 by 6, and likewise get a quotient of 6, with a remainder of 1. The difference is that the remainders are not truly the same. The first remainder is 1 part out of 4, but the second remainder is 1 part out of 6</span>
Step-by-step explanation:
-x+1>-2
3>x
6(2x-3)>-6
12x-18>-6
12x>12
x>1
