Question

3. A car travels 60 km in 45 minutes. Find its speed in km/hour.
​

Answer 1

${ \huge { \mathtt{Speed = > \frac{60 \times 24}{45} }}} \\ \\ { \huge { \mathtt{ \: \: \: \: \: \: \: \: \: \: \: \: \: = > \frac{1440}{45} = {\red{32 \: {km \: h}^{ - 1} }}}}}$

Now,

$= > (32 \times \frac{5}{18} ) \: {ms}^{ - 1} \\ \\ = > \frac{160}{18} = { \red{8.8 \: {ms}^{ - 1} }}$

Answer 2

Answer:

Step-by-step explanation:

Distance travelled by car=60km

Time taken by car=45min=45/60hr = 3/4 hr.

Speed=distance/time

60/(3/4)

Speed= 60*4/3=80km/hr
