Answer: He still has to mow 45 lawns, or 75% of the lawns before he is finished.
Answer:
8 feet per second.
Step-by-step explanation:
We have been given that a car is driving away from a crosswalk. The formula expresses the car's distance from the crosswalk in feet, d, in terms of the number of seconds, t, since the car started moving.
We will use average change formula to solve our given problem.
Therefore, the the car's average speed over the given interval of time would be 8 feet per second.

Hello!</h2>
The answer is:
The distance to over by Adam to get to the park is 108 miles.
<h2>
Why?</h2>
To solve the problem, we need to write two equations using he given information about the times and his speed.
So,
For the first equation we have: Travel to Disney Park
For the second equation we have: Travel back from Disnery Park
Then, if Adam covered the same distance going and coming back, we have:
We have that the speed when he was going to Disney Park was 27 mph.
Now, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.
Therefore, substituting the speed into the second equation, we have:
Hence, we have that the distance that Adam should cover to get to the park is 108 miles.
Havea nice day!
Answer:
- 1/2
Step-by-step explanation:
(-4/5) × (- 5/8)
- 4/5 × - 5/8
First we mulitply across
The top and the bottom.
- 20 / 40
because -4 × -5 = +20
and -5 × -8 = +40
Now we simplify the fraction
- 20 / 40
= - 2 /4
= - 1/2
Because we have to simplify it and so I divided it by 10 first.
-20 ÷ 10 = -2 and -40 ÷ 10 = -4
Then I simplified it again by dividing it by 2.
-2 ÷ 2 = -1 and -4 ÷ 2 = -2
So finally we have:
-1/2
And we cannot simplify that anymore so that is the answer.
Hope that helped!
Answer:
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
Step-by-step explanation:
Jamal's speed is of x mph.
Diego's speed is of (x + 7) mph.
Opposite directions.
This means that each hour, they will be x + x + 7 = 2x + 7 miles apart.
After 4 hours they are 68 miles apart, how fast is each traveling?
Using a rule of three.
1 hour - 2x + 7 miles apart.
4 hours - 68 miles apart.
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
