Question

The formula d = rt gives the distance d traveled in time t at rate r. A bicyclist rides at a constant rate of 22 kmph.

How many kilometers will he travel in 2.5 h?

km=

Answer 2

Can you help

Answer 3

so the rate, r, is 22 and the time, t, would be 2.5. plug them into the formula to solve for d

d = rt
d = 22(2.5)

Answer 4

which would be 55 @AriPotta

Answer 5

Yeah I will post the next question now

Answer 10

Solve the problem.

The formula d = rt gives the distance traveled in time t at rate r. If a bicyclist rides for 2.3 hours and travels 41 miles, what was her average speed?

A.
9.43 miles per hour

B.
5.6 miles per hour

C.
17.83 miles per hour

D.
38.7 miles per hour

Answer 11

Apply that formula \(d=rt\). We are given t and d. So \(\large r=\frac{d}{t}\)

Answer 12

which would be 41/2.3 ?

Answer 13

Yes?

Answer 14

So it would would be 17.82

Answer 15

Exactly

Answer 16

so c but it is 17.83

Answer 17

that's because you round up, not down. the answer is 17.826... so that would be rounded to 17.83

Answer 18

Last one

The formula P = ns gives the formula for the perimeter of a regular polygon with n sides and side length s.

What is the length of each side of a regular octagon with a perimeter of 54.4 cm? A regular octagon has 8 equal sides.

cm =

Answer 19

use the formula to solve for s

p = ns
s = p/n
s = 54.4/8

Answer 20

Which would be 6.8
