Answer:
12x=10(25+x)
Step-by-step explanation:
Jim's rate=x
Pete's rate=y
Jim and Pete lays the same number of tiles.
So we have,
12x=10y
Pete's can lay 25 more tiles than Jim per hour
We have
y=25+x
Substitute y=25+x into 12x=10y
12x=10y
12x=10(25+x)
12x=250+10x
12x-10x=250
2x=250
x=250/2
=125
x=125
12x=10(25+x) is the equation used to find the rate that Jim can lay tiles
Answer:
B) -0.4 seconds
Step-by-step explanation:
Laps: 25
Goal: -10 seconds to all 25 laps combined (10 seconds difference => -10)
divide by total laps
-10 /25 = -0.4s difference each lap
A bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.
It is required to find How many feet will it cover in 35 seconds.
<h3>What is conversion?</h3>
conversion is the process of changing the value of one form to another for example inches to millimeters, or liters to gallons. Units are used for measuring length, measuring weight, measuring capacity, measuring temperature, and measuring speed.
Given that:
1 hour = 60min×60sec = 3600 sec
1 miles = 5280 feet
16 miles = 16×5280ft = 84480 ft
3600sec ................. 84480 ft
35sec ................................ x ft
x = 35×84480/3600
=2956800 /3600
= 821.33 feet.
Hence, a bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.
