Question

distance =200km
time=2hrs20 min
find speed​

Answer 1

Correct answer:-

By using this formula, Speed = Distance/Time.

Given, Time = 2 hrs 20 mins = 1202.

Distance = 200 km = 0.2 km.

Therefore, Speed = 0.2/1202 = 0.000166389351 [Final ans].

Answer 2

Given:  Distance =$200$km, Time=$2hrs20$ min.

We have to find the speed.

As we know that the formula is used to calculate the speed is:

$Speed=\frac{Distance}{Time}$

We are solving in the following way:

We have,

Distance =$200$km, Time=$2hrs20$ min.

We know that $1 hour = 60 min.$

Therefore, $20$min = $\frac{20}{60}=\frac{1}{3}$hrs.

So, Time=$2hrs20$ min

$\Rightarrow Time=2+\frac{1}{3} \\\\\Rightarrow Time=2.33$hrs.

Now,

$Speed=\frac{Distance}{Time}$

$\Rightarrow Speed=\frac{200}{2.33} }\\\\\Rightarrow Speed=85.83$

Hence, the speed will be $85.83$km/hr.
