Hector can run 400 metres in 66 seconds. Use this information to show that he could run 5 kilometres in less than 14 minutes.

Please help!

Hector can run 400m in time period of 66 seconds

So, speed of Hector = Total distance ÷ Total time

= 400/66 => 6.06 m/s

So if we want to prove he can run 5km in 14 mins

Then Speed = Total distance / Total time

6.06 m/s = Total distance / 840 (convert mins in sec )

Transpose 840 then,

6.06 × 840 = Total distance

5090.4 meters = Total distance

5.09 km

Hence, proved that Hector could run 5km in 14 mins

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
