Question

I travel a distance of 10 km and come back in 5/2hours what's my speed​

Answer 1

Answer:

1.1 ms-1

Step-by-step explanation:

10km=10000m

5/2hours = 9000s

speed= distance(m) / time(s)

speed=10000m/9000s = 1.1 ms-1

Answer 2

Answer:

My speed is $8$ km/hr.

Step-by-step explanation:

Given : The distance traveled = $10$ km

           Time required = $\frac{5}{2}$ hr

To find : Speed =?

Solution :

• It is given that the distance traveled is $10$ km and came back in $\frac{5}{2}$ hr, it means that,
• The total distance traveled = $10+10=20$ km
• Now, to find the speed, we have a formula

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

                  = $\frac{20}{\frac{5}{2} }$

                  = $\frac{20*2}{5}$

                  = $\frac{40}{5}$

                  = $8$ km

• ∴ My speed is $8$ km/hr.
