Carrie and brent leave home at the same time. carrie drives due east at a rate of 30 mph, while brent drives due south at a rate of 60 mph. how far apart are they (to the nearest mile) after 4 hours.

Acceleration is rate of change of velocity.

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem !

Given :

v₁ = 30 mph due east

v₂ = 60 mph due south

t = 4 hours

Unknown :

displacement = d = ?
