@Mimi_x3 @mathslover @ParthKohli @pr3dat0r
@TheViper wanna try
let d = distance \[\frac{60t + 40t}{2t} \implies \frac{100t}{2t} = 50m/s\]
let t= time not d = distance
okay

lol @Rohangrr do you even know the answers to these
yes just posting having a lot of time
lol

\[Speed_{ave} = \frac{\text{total distance }}{\text{total time}}\]

total distance = 60t + 40t total time = t + t =2t
Technically, speed is\[s=|v_{avg}|=\left|\frac{\Delta x}{\Delta t}\right|\]irrelevant for this problem, though.
