Answer:

hopefully this is correct but 37.5m/s

Step-by-step explanation:

1 minute =60 secs
30 secs=1/2 min
so it will be 30/60 × 75(somewhat like cross multiplication)
btw r(speed)= distance(d) ÷ time (t)

Hello There!

Dividing a fraction is the same thing as multiplying by its reciprocal.

This means that $\frac{3}{4}$ ÷ $\frac{5}{12}$ is the same as multiplying $\frac{3}{4}$ by $\frac{12}{5}$ .

So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.

HAVE A GREAT DAY!

Students are selling hand-made magnets at the school craft fair. One magnet costs $0.30, 2 magnets cost $0.43, 3 magnets cost $0

Sliva [168]

1 = 0.30
2 = 0.43
3 = 0.56
4 = 0.69
5 = 0.82
6= 0.95

To find by how much you are adding every time , you have to subtract the 2 magnet cost (0.43) from the 1 magnet cost (0.30) and this equals 0.13
