13) John and James live 0.7km apart. If John takes 25cm steps, then how many steps would it take

aleksandrvk [35]

It will take John 2800 steps to walk from his house to James' house

Step-by-step explanation:

First of all we have to convert all the measurements in same unit.

Distance = 0.7 km

As 1 km = 1000 m

0.7*100 = 700m

And

1 m = 100 cm

700*100 = 70000cm

Now,

25 cm = 1 step

$So,\\70000cm = \frac{70000}{25}\\=2800\ steps$

It will take John 2800 steps to walk from his house to James' house
