On friday, andre biked 60 miles in 4 hours at a constant rate. on saturday, he biked at a rate that was 4 mph slower. what was his rate on saturday? a. 4 mph b. 11 mph c. 15 mph d. 16 mph

If on Saturday, he biked at a rate that was 4 mph, her rate on saturday will be 11mph. Option B is correct.

The formula for calculating unit rate is expressed as:

Unit rate = Distance/Time

Unit rate  = 60miles/4hrs

Unit rate  = 15mi/hr

This shows that Andre rate on friday is 15mi/hr

If on Saturday, he biked at a rate that was 4 mph slower, her rate on saturday will be 15-4 = 11mph

Step-by-step explanation:

You have to divide the miles / the hours = 60/4 = 15, then subtract the amount of mph he slows = 15 - 4 = 11

Answer is C

Hope this helps :)

If is correct give me brainliest pls

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
