5.6km

Step-by-step explanation:

5×7=35

160×35=5600

=5.6km

Answer 2

Given :

• Piyush walks 160 m everyday

To Find :

• Kilometres he will walk in 5 weeks

Solution :

To find that how many kilometres he will walk in 5 weeks we will first take out the number of days by multiplying 5 by 7 and then multiply the product with 160, lastly convert the product to kilometres, so let's do it!

Now, let's multiply 5 and 7, are you thinking why?

As we know that, we have to find out distance Piyush will cover in 5 weeks that's why 5 × 7, why 7 now? Because 1 week = 7 days

Now, 5 × 7 = 35 days

So, to find out the distance he will be covering in 5 weeks we will be multiplying 160 by 35, now why 160 because he walks 160 m everyday!

Now, 160 × 35 = 5600 m

So, he will be covering 5600 m in 5 weeks, wait! We haven't solved this sum completely yet

Now, we will be converting 5600 m to km

As we know that,

1 km = 1000 m

So, 5600 = ( 5600 ÷ 1000 ) 5.6 km

∴ He will walk 5.6 km in 5 weeks. So, the required option is (a)
