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

55? i think maybe

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
