Step-by-step explanation:
A cyclist travels 6 miles in 15 minutes. What is her average speed in mph?

given data
distance= 6 miles
time= 15 minutes
convert minutes to hours
15 minutes is 0.25hours
Step two:
speed= distance/time
speed= 6/0.25
speed= 24 miles per hour
2x+1=27032
2x=27031
x=13515.5
2x+3
=2(13515.5)+3
=27034
