he still need to cover? *​

Answer 1

Step-by-step explanation:

first = 1.12km in 2hour

next=1.06km in 2hour

he has cover total distance is 7/2=3.5km

1.12 km

+1.06 km

=2.18 km

total distance is 3.5km

so,

3.5 km

- 2.18km

=1.32 km he still need

Answer 2

Given that

Raj cover 1.12km in first 2hrs

then

1.06km in next 2 hrs

Total distance is

$\frac{7}{2} km$

To find

Distance need to cover

Solution

Distance he cover till now is addition of all covered distance

$covered \: distance = 1.12 + 1.06 \\ = 2.18km$

Distance still need to cover will be subtraction of covered distance by total distance

$distance \: need \: to \: cover = 3.5 - 2.18 \\ = 1.02km$

Hence he still need to cover 1.02km.
