Answer 2

Given:

distance = 1.6 km

time = 7 mins

To Find:

speed

Solution:

We Know,

Distance = Speed * Time

Now, Converting distance into meters and time into seconds

distance = 1.6 * 1000 = 1600 m

time = 7 * 60 = 420 sec

speed = distance / time

speed = 1600 / 420

speed = 80/21

speed = 3.80m/s = (3.80 )*(18/5) Km/hr = 13.68 km/hr

So, speed is 3.80 m/s or 13.68 Km/hr
