@TheViper wanna try

lgbasallote · Answer

let d = distance

$$\frac{60t + 40t}{2t} \implies \frac{100t}{2t} = 50m/s$$

lgbasallote · Answer

let t= time not d  = distance

anonymous · Answer

okay

lol @Rohangrr do you even know the answers to these

anonymous · Answer

yes just posting having a lot of time

lgbasallote · Answer

$$Speed_{ave} = \frac{\text{total distance }}{\text{total time}}$$

lgbasallote · Answer

total distance = 60t + 40t

total time = t + t =2t

anonymous · Answer

Technically, speed is$$s=|v_{avg}|=\left|\frac{\Delta x}{\Delta t}\right|$$irrelevant for this problem, though.
