Speed of a car that travels 150 km in 3.00 hrs is 30.97mi/hr

Explanation:

Given:

Distance = 150km

Time = 3hrs

To find:

Speed of the car:

Solution:

So by substituting in the equation we get that,

Speed= 50km/hr

1km/hr = (5/18)m/s

So,

speed = 50*5/18

speed=()m/s

1m/s = 2.23mi/hr

So we get that,

Speed =

speed = 30.97mi/hr

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
