  1. Given,

    Speed (s1) = 40km/h

    Time (t1) = 15 mins = (15/60) hr

    Distance d1 = (s1 × t1) = 40 × (15/60) = 10 km

    WE KNOW THAT,

    Speed (s2) = 60 km/h

    Time (t2) = 15 min = (15/60) hour

    Distance (d2) = (s2 × t2) = 60 × (15/60) = 15 km

    Total distance (d) = (d1 + d2) = 10 km + 15 km = 25 km

  2. Answer:

    [tex] \huge\star \underline{ \boxed{ \purple{Answer}}}\star[/tex]

    Time taken to cover the distance of 330km =

    [tex]\sf{4\:hours\:12\:min’s}[/tex]

    Step-by-step explanation:

    Given :

    s = 40km/hr

    d = 330 km

    and,

    speed increases by 50%

    To Find :

    Time taken to cover 330 km.

    Solution :

    ➝[tex]\sf{s_1}[/tex]= 40km/hr

    t = 1 hr

    d = ?

    ➝[tex]\sf{d\:=\:s_1\:\times\:t}[/tex]

    [tex]\sf\green{Putting\:values}[/tex]

    ➝[tex]\sf{d\:=\:40\:\times\:1}[/tex]

    ➝[tex]\sf{d\:=\:40\:km}[/tex]

    [tex]\sf\green{New\:Speed\::-}[/tex]

    ➝[tex]\sf{s_2\:=\:40\:\times\:\cancel\frac{100}{50}\:2}[/tex]

    ➝[tex]\sf\green{Now\:calculating\:time\:taken\:to\:cover\:330km\::-}[/tex]

    ➝[tex]\sf{d\:=\:330km}[/tex]

    ➝[tex]\sf{t\:=\:?}[/tex]

    ➝[tex]\sf{s_2\:=\:\frac{d}{t}}[/tex]

    ➝[tex]\sf{t\:=\:\frac{d}{s_2}}[/tex]

    ➝[tex]\sf{t\:=\:\cancel\frac{330}{80}\:4.12}[/tex]

    ➝[tex]\sf{t\:=\:4hr\:12min\:(approx.)}[/tex]

    [tex]\Large\sf\red{Hence,}[/tex]

    He will take 4 hr & 12 min to cover 330km.
