4 miles in 1/3 houra

Step-by-step explanation:

Which speed is the fastest? Group of answer choices LaTeX:

The formula for speed =

Distance (miles) / Time (hours)

A) 4 miles in 1/3 hours

= 4 / 1/3

= 4 ÷ 1/3

= 4 × 3

= 12 miles per hour

B)1/3 miles in 4 hours

=1/3 miles/4 hours

= 1/3 ÷ 4 miles per hour

= 1/3 × 1/4 miles per hour

= 1/12 miles per hour

C) 1/2 miles in 3 hours

= 1/2 miles / 3 hours

= 1/2 ÷ 3

= 1/2 × 1/3

= 1/6 miles per hour

The fastest speed is A, 4 miles in 1/3 houra

answer: the first graph

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
