Answer:
a.
b.
Step-by-step explanation:
We are given that
Speed of red bike, v=24 km/h
Speed of blue bike, v'=12km/h
Distance of red bike when t=0
=10 km north
Distance of blue bike when t=0
=6km east
a. We have to find the expression of distance of red bike from Lawrence.

Let t be the time taken by red bike
Distance of red bike from Lawrence is given by


b.
Distance of the blue bike from Lawrence


C 72°
Answer:
we have
f(c)=9/5C+32
now
22°C to °F
°C=22°
we have
f(c)=9/5C+32
f(c)=9/5*22+32=71.6≈72
answer is
<u>2</u><u>2</u><u>°</u><u>C</u><u>=</u><u>7</u><u>2</u><u>°</u><u>F</u>
N/17 = 70/50
Simplify the fraction on the right
n/17 = 7/5
Multiply both sides by 17 to isolate "n" on the left
n = 119/5
Answer choice (A) is correct.
