Answer:
The horizontal distance traveled by the projectile is 60 m
Explanation:
Given;
initial horizontal velocity of the projectile, Vₓ = 30 m/s
time of the motion of the projectile, t = 2 s
The horizontal distance traveled by the projectile is given by the range of the projection;
X = Vₓt
X = 30 x 2
X = 60 m
Therefore, the horizontal distance traveled by the projectile is 60 m

Explanation:
Given the following :
Distance between Ranjan and Gomez house = 9km
Start time = 6'o clock
Time he arrived at Gomes house = 7'o clock
Time used for chatting during this period = 5 minutes
Distance covered in 40minutes = 6km
Time spend for second part of the journey = (60 - (40 + 5))minutes = 15 minutes = 15/60 = 0.25 hoir
Distance covered during second part of journey = 9 - 6 = 3 km
Speed = distance / time
Speed = 3km / 0.25 hr = 12km/hr
Average speed for entire journey :
First part :
Speed = distance / time
Time = 40 minutes = (40/60) = 0.667 hour
Speed = 6km / 0.667 hour = 9km / hr
Average speed :
(First part + second part) / 2
(9km/hr + 12km/hr) / 2 = 21km/hr / 2 = 10.5 km/hr
= 10.5km/hr
