Given:
speed = distance / time
walking: 3 miles per hour
running 5 miles per hour
for a total of 3 hours.
3t = 5(3-t)
3t = 15 - 5t
3t + 5t = 15
8t = 15
t = 15/8
t = 1 7/8
7/8 * 60 mins = 52.50 minutes
t = 1 hour and 52.5 minutes
It took Stu 1 hour and 52.5 minutes to hike the trail one way.
Step-by-step explanation:
a. (0.60x + 0.70y)- 50 = 10
<=> 0.60x + 0.70y = 60
b. (x+y) = 5(x-y)
x+y=5x-5y
<=> 4x - 6y = 0
Each tricycle has 3 wheels and one seat, so the ratio of seats to wheels is 1:3
Answer:
Step-by-step explanation:
The circumference of a circle can be found using the following formula:
where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.
We also know we are using 3.14 for pi. Substitute it in for pi.
Multiply.
The circumference of the circle is 69.08 centimeters.
Answer:
Solution,
Let,(x1,y1)=(-4,-3)
(x2,y2)=(3,5)
Using distance formula,
AB=√(x2-x1)²+(y2-y1)²
=√(3+4)²+(5+3)²
=√49+64
=√113 units.
