Question

How long will it take a coach travelling at 90 km/h to travel 300 km along a highway?

Answer 1

Speed of coach = 90 km/h

Distance to be travelled = 300 km

Let, time = t

∵ t = s/v

⇒t = (300 km)/(90 km/h)

⇒t = 30/9 h

⇒t = 10/3 h = 3.33 h

Equations of Motion:-

1. v = u ± at
2. s = ut ± ½at²
3. ± 2as = v² - u²
4. Snth = u + a/2(2n - 1).

Answer 2

Answer:

3.33333333 /3.33 (3 significant figures)

Explanation:

Data:

Speed : 90 km

Distance: 300 m

Time : ?

Time; 300÷90 (Zero's are cancelled)

= 30 ÷ 9

= 3.33

or you can directly divide

300÷90

= 3.33
