The distance from talamunda to velcratia is 700 miles. the train takes 5 hours to travel the distance. at what unit rate is the train traveling?

Plane speed = x km/h

Wind speed = y km/h

against wind x-y 5.00 hours

with windx+y 4.00 hours

Distance = same = 4400 miles

t=d/r

4400 / (x - y) = 5.00

5 (x - y) = 4,400.00

5 x - 5 y = 4400 ... 1

4400 / (x + y) = 4.00

4.00 (x + y) = 4400

4.00 x + 4.00 y = 4400 ... 2

Multiply (1) by 4.00

Multiply (2) by 5.00

we get

20 x + - 20 y = 17600

20 x + 20 y = 22000

40 x = 39600

/ 40

x = 990 km/h

plug value of x in (1)

5 x - 5 y = 4400

4950 - 5 y = 4400

-5 y = 4400 - 4950

-5 y = - 550

y = 110 km/h

140 miles per hour

Divide 700 and 5

It will give you 140
