Question

time=3:45 hours dustance =240km speed =?​

Answer 1

Answer:

distance= 240km

time=3:45 hours

= 3.75 hours

Speed = distance/time

= 240/3.75

= 2400/375

= 64km/hour

Answer: 64Km/hr

Answer 2

Given :-

• Time = 3:45 hours
• Distance = 240 km

To find :-

• Speed = ?

Solution :-

• Firstly, convert 3 hrs and 45 mins into hour.

As we know,

1 hr = 60 mins

• Divide 45 mins by 60.

$\implies\sf{\dfrac{45}{60}}$

$\implies\sf{0.75~hours}$

• Time = (3 + 0.75) hr = 3.75 hrs

______________________________________

$\sf\boxed{\huge \: Speed~=~{\dfrac{Distance}{Time}}}$

Put the given the values.

$\sf{\dfrac{240}{3.75}}$

$\sf{Speed~=~64~km/hr}$

• Speed = 64 km/hr
