An airplane took four hours to fly 1,500 miles. how many hours will it take the airplane to fly 2,100 miles if it flies at the same speed?

5.6 hours

Step-by-step explanation:

Divide 1500 by 4. This tells you the plane is going 375 miles per hour.

Now divide 2100 by 375. This tell you the plane will take 5.6 hours to travel 2100 miles.

5.6

Step-by-step explanation:

mph = m/h

mph = 1,500/4

mph = 375

375 = 2,100 /h

375h = 2,100

h = 2,100/375

h = 5.6

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
