Answer 2

Step-by-step explanation:

T=4/3hr and D=8km

S=D/T

Put the value of T and D,

We get

S=6km/hr.

a) (i) 6*1000*10)/60=1000m=1km (In 10min)

(ii) 6*1000*30/(60*60)=50m

b) (i) Time taken in 2500m =2500/1000*6

=5/12hrs.=5*60/12 =25minutes

(ii) Time taken in 6.5km

=6.5/6 =65/60 = 1.0833hours
