Answer:

80 × 100 =8000

15+15=30

30÷8000=266.666666666677

Answer 2

$\sf \purple{for \: first \: 15mins : }$

$\sf speed = 80kmph$

$\sf time = 15min = \frac{1}{4} hr$

$\boxed{ \red{\bf speed = \frac{distance}{time} }}$

$\implies \sf distance = speed \times time$

$\implies \sf distance = 80 \times \frac{1}{4}$

$\therefore \sf distance = 20 \: km$

$\sf \purple{for \: next \: 15mins : }$

$\sf speed = 100kmph$

$\sf time = 15min = \frac{1}{4} hr$

$\sf distance = 100 \times \frac{1}{4}$

$\sf distance = 25 \: km$

$\sf \orange{total \: distance = 20km + 25km = \underline{\underline{45km}}}$
