(1)1.75 km (2) 1.60 km (3) 1.55 km (4) 1.65km​
answer 1.75 km

Answer 1

option 4

Step-by-step explanation:

area covered by wheel in one revolution = circumference of the wheel = 2×22/7×radius of the wheel

area covered in one revolution= 2×22/7×2.1/2

=6.59 meters

area covered in 250 revolution= 6.59×250

= 1650meters

options are in km so when divide it by 1000 we get 1.65km

check it again answer must be option 4
