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 1

the answer is obvious I mean you cant go 38.7 mph on a bike or 17.83 mph

Answer 2

o

Answer 3

ok... the equation to find the distance is
distance = time x rate...
which is
d = rt
if we want to find the rate .. we can write it as
rate = distance / time
which is
r = d/t
where
d = distance = 41 miles
t = time = 2.3 hours
so...
r= 41/2.3 = 17.83 miles per hour
