Question

The total mileage for Wayne's trip is 420 miles. So far, he has traveled 180 miles in 3 hours. Wayne will continue his trip at this rate of speed.
Which expression shows how long it will take Wayne to complete his trip?

(420+180)÷(180÷3)

(420−180)÷(180÷3)

(420−180)+(180÷3)

(420−180)÷(180−60)

Answer 1

It isalittle hard to explain but, in the most simplest way, i did the math, I found out the total amount of hrs it took in total. The hrs i added where 4 so, if u do the math on all the choices, only answer B gives you 4, therefor the answer is B.
