Ayaan travels 90 miles at an average speed of 60 mph.
She then travels a further 40 miles.
The average speed for the entire journey is 59 mph.

god please help im dumb asf
90 / 60 = 1.5 hr
(90 + 40) / (t + 1.5) = 59
solve for t
final 40 mile average speed is ... s = 40 / t
(90 + 40) / (t + 1.5) = 59
solve for t
final 40 mile average speed is ... s = 40 / t
