Answer 1

Answer:

$79\frac{1}{3}\ \frac{feet}{second}$

Step-by-step explanation:

we know that

$1\ hour=3,600\ seconds$

To convert hour to seconds multiply by 3,600

$1\ mile=5,280\ feet$

To convert miles to feet multiply by 5,280

In this problem we have

$50\ \frac{miles}{hour}$

Convert to ft/sec

so

$50\ \frac{miles}{hour}=50(\frac{5,280}{3,600})=\frac{264,000}{3,600}\ \frac{feet}{second}$

Simplify

$\frac{220}{3}\ \frac{feet}{second}$

Convert to mixed number

$\frac{220}{3}\ \frac{feet}{second}=\frac{219}{3}+\frac{1}{3}=79\frac{1}{3}\ \frac{feet}{second}$
