Answer:
20 seconds
Step-by-step explanation:
speed = distance/time
distance = speed * time
The faster racer will catch up to the slower racer in x meters ahead of the slower racer.
The faster racer is 40 meters behind the slower racer, so he travels x + 40 until he catches up.
Slower racer:
speed = 12 m/s
distance = x
time = t
Faster racer:
speed = 14 m/s
distance = x + 40
time = t (the same time as the slower racer)
Slower racer:
distance = speed * time
x = 12t
Faster racer:
x + 40 = 14t
System of equations:
x = 12t
x + 40 = 14t
Since the fist equation is already solved for x, substitute 12t for x in the second equation and solve for t.
12t + 40 = 14t
40 = 2t
20 = t
t = 20
The faster racer catches up in 20 seconds.
In these types of questions, it’s best to Guess and Check.
88(2) – 124 = 52
88(8) – 124 = 580
Therefore... the correct option is y = 88x – 124
Hi there!
Answer:
<u><em>=5,000,000</em></u>
Step-by-step explanation:
This question is about pemdas.
P-parenthesis
E-exponents
M-multiply
D-divide
A-add
S-subtract
*its should be go left to right.*
5*10⁶
calculate with exponents first.
10⁶=10*10*10*10*10*10=1,000,000
5*1,000,000
=5,000,000
Hope this helps!
