Question

how do i find out the maximum speed and things? also, if you can give the answer and tell me why that would be amazing!!

Answer 1

Answer:

See the answers and the explanation below.

Explanation:

To solve these questions we must understand that speed is the relationship between the displacement and the time that the displacement lasts.

1. 300 [km], in 5 [hr]

d = displacement [km]

$v = d/t$

where:

v = velocity [km/h]

t = time [hr]

$v = 300/5\\v = 60 [km/h]$

In one hour : $d = 60*1\\d = 60 [km]$

b. Car B 100 [km] in 2 [hr]

$v =100/2\\v = 50 [km/h]$

C. The car A has the greatest average speed.
