Question

an athelete can jog 3 km in 15 minutes . at the same speed how long woud it take him to jog 2 km ?

Answer 1

speed = distance / time = 3000/0.5 = 6000m/s
time taken to cover distance of 2km or 2000m,
time = distance / speed = 2000/6000 = 1/3 sec.

if it seems to be helpful mark me as brainliest.

Answer 2

Answer :

10 min

Step-by-step

3 km jog = 15 min

2 km jog = x

x = 15 × 2

x = 30

x = 30/3

= 10

Therefore, x = 10 min
