Answer:
971 m to nearest metre
Step-by-step explanation:
training distance = 5*2*(260 + 480) m Â
Diagonal distance = √(2602 + 4802) m
Heavy rain training distance = 5*(260 + 480 + √(2602 + 4802)) m
Difference between these:
Â
5 × 2  × ( 260 + 480 ) - 5 ×( 260 + 480  + √ 260 ^ 2 + 480 ^ 2 )
  = 970 . 5311872087638744
Â
difference = 971 m to nearest metre
Hope this answer helps you :)
Have a great day
