red bike is traveling south, toward Lawrence, at constant speed of 24km/h and a blue bike is also traveling east, away from Lawr

zavuch27 [327]

Answer:

a. $R=10-24t$

b. $B=6+6t$

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.

$Distance=speed\times time$

Let t be the time taken by red bike

Distance of red bike from Lawrence is given by

$R=10-24\times t$

$R=10-24t$

Distance of the blue bike from Lawrence

$B=6+6\times t$

$B=6+6t$
