Two trucks A and B travelling at 26km/hr and 28km/hr respectively approach one another on a straight road. Truck A is 10m long, while truck B is 15m long. Determine the time in seconds that elapse before the trucks completely pass each other (3 marks)

Malori yanakaribiana, kwa hivyo kasi zao huongezwa pamoja ili kupata kasi ya jamaa.
Kasi ya lori A ($v_A$) = 26 km/hr
Kasi ya lori B ($v_B$) = 28 km/hr
Kasi ya jamaa ($v_{rel}$) = $v_A + v_B = 26 \text{ km/hr} + 28 \text{ km/hr} = 54 \text{ km/hr}$

Ili kubadilisha km/hr kuwa m/s, zidisha kwa $\frac{1000}{3600}$ au $\frac{5}{18}$.

Ili malori yapitane kabisa, umbali wa jumla unaopaswa kufunikwa ni jumla ya urefu wao.
Urefu wa lori A ($L_A$) = 10 m
Urefu wa lori B ($L_B$) = 15 m
Umbali wa jumla ($D$) = $L_A + L_B = 10 \text{ m} + 15 \text{ m} = 25 \text{ m}$

Muda ($t$) = Umbali / Kasi ya Jamaa

Muda unaohitajika ni $\frac{5}{3} \text{ sekunde}$.
