Answer:
<em>24 minutes</em>
<em></em>
Step-by-step explanation:
Given:
Distance per lap = 2 miles
Speed of Lou Lambert = 160 miles/hr
Speed of Ralph Redding = 170 miles/hr
Speed difference between the two = 170 - 160 = 10 miles/hr
Therefore, we can say that <em>Ralph gains 10 miles in 60 minutes </em>over Lou<em>.</em>
We have to find the time in which Ralph will gain 2 laps i.e. 2 2 = 4 miles.
Let us use unitary method to find the required time.
10 miles are gained by Ralph in 60 minutes
1 mile will be gained in
4 miles will be gained in 6 4 = <em>24 minutes</em>
Answer:
76
Step-by-step explanation:
A + B = 127
5.80A + 4.25B = 657.55
Solve with substitution.
5.80A + 4.25(127 − A) = 657.55
5.80A + 539.75 − 4.25A = 657.55
1.55A = 117.80
A = 76
Answer:
A
Step-by-step explanation:
8 times 1.75 is 14.
Commutative property is "a + b = b + a"
Therefore your answer is 1. 5 + 6 = 6 + 5
