Distance = d = 1240 m
Time = T = 60 s
Speed = v = 5 m/s
distance covered in 60 seconds = 5 × 60 = 300 m
distance to be covered = 1240 m
so time= distance/speed= 1240/5 = 248 seconds
Now 248-60 = 188 seconds
so after a ride of 60 seconds it will take Brandi to take 188 more seconds to arrive at her house.
until or unless she stops by to buy some food for her or click a selfie!
