Answer 2

Answer:

1.5 hours

Step-by-step explanation:

Firstly we calculate the distance based od the given quantities,

speed= distance/time

60=d/2

d=60 x 2= 120

Therefore the distance is 120 km.

Now using this information we can find the time of the second case

speed= distance/time

80=120/t

t=120/8

t=3/2 = $1\frac{1}{2}$

Therefore it will take 1.5 hours
