Mathematical Problem?

Question

Laura jogs at least 1500 meters everyday on a circular track. If the track has a diameter of 80 meters, about how many rounds does Laura jog everyday?

Answer 1

ok so when your dealing with diameter that means you add and if every 80meters theres a twist so just add 80+80= untill u get 1500 =] goodluck!

Answer 2

jog at least 1500m means she can also jog more than 1500. agree?

1500/80 = 18.75 rounds (which i dun tink is the ansas how are u supposed to measure .75 rounds):)

try this

case 1 : let's take 18 rounds

18x80=1440    hence it is not the ans as it must be at least 1500 rounds

case 2: let's take 19 rounds

19x80=1520    ta da this is the ans   Ans: 19 rounds

Answer 3

Laura jogs at least 1500 meters everyday on a circular track. If the track has a diameter of 80 meters, about how many rounds does Laura jog everyday?

Anna here it is

Circumferential Dimension of the Track = π D

Circumferential Dimension of the Track = π (80)

Number of round Laura Jog everyday = 1500 / π(80)

Number of round Laura Jog everyday = 5.97 rounds

or approximately 6 rounds per day

hope this helps
