Answer 1

Answer:

29.22 km/h

Step-by-step explanation:

Distance covered = 526 /5

time taken = 18/5

v = s/t

v = 526/5 ÷ 18/5

v = 526/5 × 5/18

v = 29.22

Answer 2

Answer:

Distance covered by the car = 378.72 km

Step-by-step explanation:

Given,

• Speed of the car = $\sf 105 \dfrac{1}{5} \ km/h$

To find,

• distance covered in $\sf 3 \dfrac{3}{5} \ hours$

Solution,

➣ Speed of the car,

  $\sf v=105 \dfrac{1}{5} \ km/h \\\\ v=\dfrac{526}{5} \ km/h$

➣ Time taken,

  $\sf t= 3 \dfrac{3}{5} \ hours\\\\\\ t=\dfrac{18}{5} \ hours$

we know,

  $\boxed{\bf Speed = \dfrac{Distance \ covered}{time \ taken}} \\\\ \sf Distance \ covered=Speed \times time \ taken$

Substituting,

Distance covered

          $\sf = \dfrac{526}{5} \ km/h \times \dfrac{18}{5} \ h\\\\ = (105.2 \times 3.6) \ km \\\\ =378.72 \ km$

Therefore,

Distance covered by the car = 378.72 km
