Answer :
❍ Distance covered in 1.5 hours :
[tex]:\implies\tt\:distance=speed\times time[/tex]
[tex]:\implies\tt\:d_1=v_1\times t_1[/tex]
[tex]:\implies\tt\:d_1=30\times 1.5[/tex]
[tex]:\implies\bf\:d_1=45\:miles[/tex]
❍ Distance covered in 2 hours :
[tex]:\implies\tt\:distance=speed\times time[/tex]
[tex]:\implies\tt\:d_2=v_2\times t_2[/tex]
[tex]:\implies\tt\:d_2=40\times 2[/tex]
[tex]:\implies\bf\:d_2=80\:miles[/tex]
❍ Total distance covered by body :
- d = d₁ + d₂
- d = 45 + 80
- d = 125 miles
