Question

plz answer question 9

Answer 1

given d 422/3 and t 13/2

so , spped = d/t

=422/3/13/3

=422/13

then , d = s.t

422/13. new time

422/13.13/2

211

Answer 2

speed=4 1/3 hours

=13/3 hours

distance=140 2/3

=422/3

S=D/T

T=S×D

13/2=x×x

2x=13/2

x=13/2×2

=13

speed =13/km

distance=13km
