It takes a person 50 minutes to get to campus. he spends t minutes walking to the bus stop and the rest of the time riding the bus. his walking rate is 0.06 miles per minute and the bus travels at a rate of 0.5 miles per minute. the total distance walking and traveling by bus is given by the algebraic expression 0.06 t plus 0.5 (50 minus t ).

a) d(t)  =  25 - 0.44t

b) d(t)  =  16.2 mles

Step-by-step explanation:

Question incomplete.

From google, I found two question

a) Simplify algebraic expression

b) Use each form of the algebraic expression to determine the total distance that you travel if you spend 20 minutes walking to the bus stop

a)

d(t)  =  0,06 t + 0.5 ( 50 - t)

d(t)  =   0,06 t + 25 - 0,5t

d(t)  =  25 - 0.44t

b)

d(t)  =  25 - 0.44t        for t = 20 min

d(t)  =  25 - 0.44*(20)

d(t)  =  25 - 8.8

d(t)  =  16.2 mles

i think 5 miles per hour
