Motion Problem Exercise Answer Key and Solution

Here’s the answer key and complete solution for Motion Problem Exercise 1.
1.) 1, 800 Kilometers

Distance = ?
Rate = 400 kph
Time = 4.5 hours

$d = r \times t$
$d = 400 \ times 4.5$
$d = 1, 800 km$

2.) 12 kph

Distance = 3 km
Rate = ?
Time = 15 mins (or 2.5 hrs)

$rate = \dfrac{distance}{time}$
$rate = \dfrac{3}{.25}$
$rate = 12 kph$
