Question

If 1 yd equals 3 ft in one mile equals 500 280 ft how many yards are there in 4 miles.

Answer 1

1 yd ----------------------- 3 ft

1 mi ----------------------- 5280 ft

number of yards = ? 4 mi

Then

1 mi ----------------------- 5280 ft

? mi ---------------------- 3 ft

x = (3 x 1) / 5280

x = 5.68 x 10^-4 mi

5.68 x 10^-4 mi --------------------- 1 yd

4 mi --------------------- ?

x = (4 x 1) / 5.68 x 10^-4

x = 7040 yd
