Answer 1

Step-by-step explanation:

Their are two methods

1.

Given : Distance covered by Anica = 2km

Time required to cover 2km =155 min

To Find : How much time Anica will take to cover the distance of 3 1/2km.

Solution: So first we have to find out how much time she took to cover the distance of 1km.

: 1km = 155mins ÷ 2km

= 77.5

: 1km = 77.5min.

Therefore time taken to cover 3 1/2km =

77.5×3.5 = 271.25

Therefore, Anica will take 271.25mins to cover the distance of 3 1/2km

OR

Fast steps

2km = 155mins

3.5km = ?

Now do cross multiplication

2×x = 3.5×155

x = 542.5÷2

x = 271.25
