Question

A car travels 60km in 45 minutes. Find its speed in km/hr?

Answer 1

distance travelled by car = 60km
time taken by car = 45min. = 45/60 hr = 3/4 hr.
speed = distance/time
         = 60/(3/4)
speed = 60*4/3 = 80km/hr.  

Answer 2

Answer:

$Speed \: of \: the \: car \\=</p><p>80\:{km}/{hr}$

Step-by-step explanation:

Speed of the car

= $\frac{Distance \: travelled}{Time \: taken }$

=$\frac{60 \: km }{45 \: minutes }$\* given *\

= $\frac{60\:km }{45 \times \frac{1}{60}\: hours }$

= $\frac{60\:km \times 60}{45\: hours }$

= $80\: {km}/{hr}$

Therefore,

$Speed \: of \: the \: car \\=</p><p>80\:{km}/{hr}$
