An island is 3 kilometers due north of its closest point along a straight shoreline. A visitor is staying in a tent that is 13 kilometers east of that point. The visitor is planning to go from the tent to the island. Suppose the visitor runs at a rate of 8 kmph and swims at a rate of 1 km. How far should the visitor run to minimize the time it takes to reach the island

150.6

all i did was i multiplied 5.02 by 30

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
