The function d(x)=1375-110x represents the distance (in miles) in a high-speed train is from its destination after x hours a. how far is the train from its destination after 8 hours? b. how long does the train travel before reaching its destination

velocity of van = 55 km/h

velocity of plane towards boy = 2 km/h

since boy is inside the van so boy will also travel with same speed as that of van

speed of boy = 55 km/h

now relative speed of plane with respect to boy

speed is boy is opposite to the plane speed so it is taken to be negative

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer
