Question

Use the known ratios to answer the following.

1 inch = 2.54centimeters
meter = 39.37inches
1 mile = 5280 feet
1 mile = 1760 yards
1mile = 1.609kilometers

Part A: How many feet are in 50 miles?

Part B: How many miles are in 88,000 yards?

Answer 1

Part A: there are 264,000 feet in 50 miles.

Part B: there are 50 miles in 88,000 yards.

Explanation:

Part A:

1 mile = 5280 feet

50 miles= x

Hence,

`\displaystyle\\x=(50*5280)/(1) \\\\x=50*5280\\\\x=264,000\ feet`

Part B:

1 mile = 1760 yards

x miles=88,000 yards

Hence,

`\displaystyle\\x=(88,000*1)/(1760) \\\\x=(88,000)/(1760) \\\\x=(1760*50)/(1760) \\\\x=50 \ miles`
