Savannah and Sarah are planning on riding their bikes to a point located at 1100 ft from their house their bicycle tires have a
1 answer:
Answer:
323.2 revolutions (324 revolutions (rounded) )
Step-by-step explanation:
Savannah has to cover 1100 feet
Sarah has to cover 1100 feet
Now,
For Savannah:
diameter is 26 in, so radius will be 26/2 = 13 inches
Circumference (1 rev) =
There are 12 inches in 1 feet, so distance to be covered in inches:
1100 * 12 = 13,200 inches
Number of revolutions = 13,200/81.68 = <u>161.6 revolutions</u>
For Sarah, it is the same so:
161.6 revolutions
Together:
161.6 + 161.6 = 323.2 revolutions to cover the whole distance (both)
Rounded, it is About 324 revolutions

Distance traveled by Train W = 1600 miles
Distance traveled by Train Z = 2,000 miles
Step-by-step explanation:
Given:
Time taken for Train W to complete a trip = 20 hours
Time taken for Train Z to complete a trip = 25 hours
The city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to.
both trains have same speeds and start from same location.
To find the distance in total each train travels.
Solution:
<em>Let length of the trip of Train W be </em>= miles
Speed of Train W can be given as :
⇒
⇒
<em>So, the length of the trip of Train Z will be</em> = miles
Speed of Train Z can be given as :
⇒
⇒
Since the speeds are same, so the equation to find can be given as:
⇒
Solving for
Multiplying both sides by 100 to remove fractions.
⇒
⇒
Using distribution.
⇒
Subtracting both sides by
⇒
⇒
Thus, Distance traveled by Train W = 1600 miles
Distance traveled by Train Z = = 2,000 miles
