In this question, we're trying to find how many miles a car travels in 15 minutes.
We know that the car travels at 85 mph.
However, we need to know how many miles it travels per minute.
To find this, we would divide 85 by 60.
85 ÷ 60 = 1.4166
The car drives at a speed of about 1.42 per minute.
We need to know how far it goes in 15 minutes, so multiply 1.42 by 15.
1.42 · 15 = 21.3
The car travels at a approximately 21.3 miles in 15 minutes.
Answer:
miles divided by gallons
car A= 115÷5=23 miles per gallon
car B= 126÷6=21 miles per gallon
Car A gets better gas mileage.
Answer:
10.5 hours.
Step-by-step explanation:
Please consider the complete question.
Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 14 hours to drain the pool by itself, how long will it take the newer pump to drain the pool on its own?
Let t represent time taken by newer pump in hours to drain the pool on its own.
So part of pool drained by newer pump in one hour would be
.
We have been given that it takes the older pump 14 hours to drain the pool by itself, so part of pool drained by older pump in one hour would be
.
Part of pool drained by both pumps working together in one hour would be
.
Now, we will equate the sum of part of pool emptied by both pumps with
and solve for t as:








Therefore, it will take 10.5 hours for the newer pump to drain the pool on its own.

4 • (2 + 5)^2 - 52
= </span>4 • (7)^2 - 52
= 4 • 49 - 52
= 196 - 52
= 144
if multiply by 2
4 • (2 + 5)2 - 52
= 4 • (7)2 - 52
= 4 • 14 - 52
= 56 - 52
= 4
Answer: A
Step-by-step explanation:
15/5 = 3
3*2 = 6
6/15 = 40%
2/5 = 40%
