D = 0.5 + 20x + 0.5v
Initial distance covered d1 = 0.5km
If she rode a bicycle for x hours at an average speed of 20 kilometers per hour, then her distance during thus period is,;
Speed = Distance/Time
Distance d2 = speed × time
d2 = 20x
If she ran for 0.5 hour at an average speed of v kilometers per hour, her distance this time will be;
Distance d3 = 0.5v
If her total distance is D, then;
D = d1+d2+d3
D = 0.5 + 20x + 0.5v
Hence an equation that relates D, x, and v is D = 0.5 + 20x + 0.5v

Answer:
this is false. hope this helps
Answer:
q = 7p
Step-by-step explanation:
given q is directly proportional to p then the equation relating them is
q = kp ← k is the constant of proportion
To find k use the condition q = 28 when p = 4 , then
28 = 4k ( divide both sides by 4 )
7 = k
q = 7p ← equation of proportion
One rotation for every 24 hours can be expressed like so:
1:24 - Times earth rotates about its axis to the time it took in hours
