1. 360 km
2. 2 seconds
Step-by-step explanation:
<h3><u>Question 1</u></h3>
<u />
<u>Formula</u>
distance = speed × time
Given:
- speed = 120 km/h
- time = 3 hours
⇒ distance = 120 × 3 = 360 km
----------------------------------------------------------------------------------
<h3><u>Question 2</u></h3>
Given:
- initial velocity (u) = 0 m/s
- final velocity (v) = 20 m/s
- acceleration (a) = 10 m/s²
To find time (t), use the SUVAT equation: v = u + at
⇒ 20 = 0 + 10t
⇒ 20 = 10t
⇒ t = 20/10
⇒ t = 2 s
120 x 3= 360(km)
20/10=2(seconds)
