Question

the distance covered by a jogger with an average speed of 2.5 ms-1 in 1.5hr is​

Answer 1

Answer:

13.5 km.

Explanation:

Distance = ?

Speed = 2.5 ms⁻¹

Time = 1.5 hour

1 hour = 3600 secs

1.5 hours = 1.5 * 3600 = 5400 secs

Distance = Time * Speed

Distance  = 5400 * 2.5

= 13500 m

1000 m = 1 km

13500 m = 13500 / 1000 = 13.5 km

So, the jogger covers a distance of 13.5 km.

Answer 2

Answer:

1hr=60 min

1min= 60 sec

Therefore: 1.5 hr = 1.5 × 60 × 60

1.5hr = 5400 sec

speed=distance/time

2.5=distance/5400

distance=13500 meter

Distance = 13.5 km

jogger covers 13500 meter(13.5 km ) distance in 1.5 hr
