Answer :

ANSWER

No, she won't catch the bus on time.

EXPLANATION

Pav gets up at 7.10 am and spends 45 minutes getting ready. 45 minutes from 7.10 am is,

[tex]7h10\min +45\min =7h(10+45)\min =7h55\min [/tex]

Then she spends 5 minutes looking for her umbrella. 5 minutes from 7.55 am is,

[tex]7h55\min +5\min =7h(55+5)\min =7h60\min =8h[/tex]

Then, she puts out the washing for another 15 minutes. 15 minutes from 8 am is,

[tex]8h0\min +15\min =8h(0+15)\min =8h15\min [/tex]

And then, she has a 6-minute walk to the bus stop. 6 minutes from 8.15 am is,

[tex]8h15\min +6\min =8h(15+6)\min =8h21\min [/tex]

Pav will get to the bus stop at 8.21 am and, therefore, she will not catch the bus on time.
