<h2>
Explanation:</h2>
We know some facts:
- There is a toll plaza every 12 1/2 miles along a 300 mile road.
- At each toll plaza drivers must pay $1.25.
First of all, we have to convert the mixed fraction into improper fraction:
Next, let's calculate the total number of toll plaza along the way:
As in every toll plaza, the driver must pay $1.25 then the total cost to drive the whole length of the road is:

Answer:
32year
Step-by-step explanation:
let Ahmed be x years then sheriff will be x+8
in 7years time
sheriff will be x+8+7=x+15
Then Ahmed will be x+7
sum of their ages will be 7\10×100=70years
x+15+x+7=70
collect like terms
2x+22=70
2x=70-22
2x/2=48/2
x=24years
Sheriff=24+8
32years
Step-by-step explanation:
1. 10-(2+3) = 5
2. 2x3 - 10 = -4
3. 3 x (4-2) = 6
4. (3+5) / 4 = 2
5. (5-2) x 3 = 9
6. (9-4) + 5 = 10
You are given
a distance of 20 kilometers and time of 30 minutes. You are required to find
for the speed of the travelling object. The equation for speed is distance over
time. Speed is a scalar quantity. It tells you the direction of the travelling object.
The solution in this problem is,
Speed =
distance/time
Speed = 20
kilometers / 30 minutes
<u>Speed =
2/3 kilometers per minute or 0.667 kilometers per minute</u>
<span>Therefore,
the speed of the object is 0.667 km per minute.</span>
